 This problem is caused by a missing fallback implementation in the PHP method FCKeditor::createHTML(). Even if '''JavaScript''' is disabled this function returns an output to display the FCKeditor's IFrame, which only works if JavaScript is enabled. Infact you're not able to get information in PHP if JavaScript is enabled or not, so we have to do a little workaround for a fallback by using the good old [noscript] tag. To keep the FCKeditor's files updatable, it's recommanded to extend the main class. And this is, how it works:
 <pre>// include FCKeditor's main class
 require_once 'fckeditor/fckeditor.php';

 // print the editor's code

 </pre>
 Now, if JavaScript is enabled the FCKeditor is displayed as usual, otherwie ther will be a textarea.

 Firefox has very rigid security features that blocks script based application, like FCKeditor, to have access to the computer clipboard. So, when using this browser, it is quite common to see a warning like the following when clicking in the “Cut” button on the toolbar:
-''"Your browser security settings don’t permit the editor to automatically execute cutting operations. Please use the keyboard for that (Ctrl+X)"''
+To make the configurations easy and very intuitive (integrated with the FCKeditor interface), we recommend the [https://addons.mozilla.org/en-US/firefox/addon/852 AllowClipboard Helper extension].

		+	=== <span id="17">With ASP.NET, I need to submit twice when using the RequiredFieldValidator in a FCKeditor instance</span> ===
		+
		+	FCKeditor will not work properly with the Required Field Validator when the "EnableClientScript" property of the validator is set to "true" (default). Due to a limitation in the default validation system, you must set it to "false".
		+
		+	If you want to do client side validation, you must use a Custom Validator instead and provide the appropriate validation function, using the FCKeditor JavaScript API.

		+
		+	IE support for this option is provided via a .htc behavior. On my server, however, the mime-type for .htc files was not set correctly and so IE was not using them (see the Microsoft Knowledge Base article at http://support.microsoft.com/kb/306231). Adding the line:
		+	<pre>
		+	AddType text/x-component .htc
		+	</pre>
		+	to my .htaccess file resolved this problem.

		+
		+	Firefox has very rigid security features that blocks script based application, like FCKeditor, to have access to the computer clipboard. So, when using this browser, it is quite common to see a warning like the following when clicking in the “Cut” button on the toolbar:
		+
		+	''"Your browser security settings don’t permit the editor to automatically execute cutting operations. Please use the keyboard for that (Ctrl+X)"''
		+
		+	There are ways to configure Firefox, granting the necessary permissions to FCKeditor to make pasting operations. Detailed info can be found here:
		+	http://kb.mozillazine.org/Granting_JavaScript_access_to_the_clipboard
		+
		+	To make the configurations easy and very intuitive (integrated with the FCKeditor interface), I recommend the following extension:
		+	http://allowclipboard.foxinus.cz/
		+
		+	=== <span id="12">Blank popups (e.g. from Source button) with Gecko browsers (!SeaMonkey, Firefox, ...)</span> ===
		+
		+	It must have been some extension which set the preference '''capability.policy.default.Window.resizeTo''' to the value '''noAccess'''. The preference does not appear in about:config, so it's even harder to detect. I found it by going through prefs.js (located in the folder of the respective profile).
		+
		+	=== <span id="13>The toolbar doesn't load in Firefox and I get an error message in the console: this.DOMDocument has no properties</span> ===
		+
		+	This problem is usually due to your server doesn't returning the proper MIME type for the .xml files (fck_styles.xml). You can verify that removing the styles combo from the toolbar and loading again the editor (after clearing the cache) fixes the problem.
		+
		+	The problem can be due to different reasons at the server side:
		+	* Mime type not configured for .xml files, can be solved in Apache by putting a .htaccess file into the base directory with the following:
		+	<pre>
		+	Addtype text/xml .xml
		+	</pre>
		+	* Restriction to use .xml files due to security concerns. You'll need to set up another extension as text/xml and use that or use a dinamic page with the proper content type.
		+
		+	'''NOTE''': It should be better if the editor was coded to handle this error and show a warning message instead of silently failing.
		+
		+	=== <span id="14">The editor's content is empty when submitting the editor's surrounding form by ajax. What is wrong?</span> ===
		+
		+	This problem is caused by a missing call of the function '''FCK.UpdateLinkedField()'''. By submitting the editor's surrounding form with an ajax function the values of all form elements are collected in a javascript object (some kind of an array). At this time the value of the hidden field that usually contains the editor's html output is empty, because the editor's surrounding form wasn't submitted for real, you can call it a simulated submit. The workaround is to call the FCK.UpdateLinkedField() function before submitting the form. Either you call it directly before the ajax collect function or in the onClick attribute of the submit button. For general use, even if you have more than one FCKeditor instance, I wrote the following hack to solve the problem.
		+	<pre>
		+	// Some Class
		+	function MyClass()
		+	{
		+	this.UpdateEditorFormValue = function()
		+	{
		+	for ( i = 0; i < parent.frames.length; ++i )
		+	if ( parent.frames[i].FCK )
		+	parent.frames[i].FCK.UpdateLinkedField();
		+	}
		+	}
		+	// instantiate the class
		+	var MyObject = new MyClass();
		+	</pre>
		+	Now can call this method in the onSubmit attribute of the editor's surrounding form <u>before</u> calling the ajax collecting function:
		+	<pre>
		+	<form ... onSubmit="MyObject.UpdateEditorFormValue(); Ajax.Collect(); return false;">
		+	</pre>
		+	'''NOTE''': the previous syntax won't work if using VisualStudio 2005 and Atlas and IE. It will be ok to use:
		+	<pre>
		+	<form ... onSubmit="MyObject.UpdateEditorFormValue(); return true;">
		+	</pre>
		+	Or you'll do it in the onClick attribute of the submit button, which is also called before the onSubmit event:
		+	<input type="submit" ... onClick="MyObject.UpdateEditorFormValue();" />

Make sure that the include statement for the fckeditor.asp file is before all other code on your page.

		+
		+	=== <span id="5">Why do I get a "Page Cannot Be Displayed" error wherever I place the code to start the editor?</span> ===
		+
		+	This can be caused because your code is not pointing the editor to the directory where the editor core (the main JavaScript file of the editor) has been installed on your server.
		+
		+	By default, the editor is configured to work in the "FCKeditor" folder at you web site root. You can easily change it by setting the BasePath property in your code when creating an instance of the editor. This is a sample code for ASP:
		+	<pre>
		+	<%
		+	oFCKeditor.BasePath = "/fckeditor/"
		+	%>
		+	</pre>
		+
		+	=== <span id="6">Internet Explorer complains of a JavaScript error and no toolbar shows. Why?</span> ===
		+
		+	Possibly check in your configuration file '''fckconfig.js''' for errors. The custom toolbar setting line labeled '''FCKConfig.ToolbarSets[ "Default" ]''' is a common place to have an error. An extra comma is the most probable problem.
		+	<pre>
		+	FCKConfig.ToolbarSets["Default"] = [
		+	['Source','-','Save','NewPage','Preview'],
		+	...
		+	['Style','FontFormat','FontName','FontSize'],
		+	] ;
		+	</pre>
		+	Should be:
		+	<pre>
		+	FCKConfig.ToolbarSets["Default"] = [

		+
		+	=== <span id="7">The Built In File Browser causes my IIS to stall/hang.</span> ===
		+
		+	If you are developing a project on a server with McAfee Antivirus software running, chances are good that the problem lies in part with the antivirus software. Try disabling ScriptStopper. ScriptStopper is trying to protect your computer from malicious scripts that will access your file system. Do not forget to re-enable ScriptStopper once you are finished.
		+
		+	For information on enabling/disabling ScriptStopper, see your help files or McAfee's online documentation.
		+
		+	This same problem may be true for Norton Antivirus, but I have not tested with that.
		+
		+	=== <span id="8">With ASP.Net, I'm having a "Cannot execute code in freed script" JavaScript error.</span> ===
		+
		+	Try to turn off SmartNavigation.
		+
		+	=== <span id="9">After configuring Speller Pages, Internet Explorer gives strange script errors.</span> ===
		+
		+	Make sure your server is not running PHP in safe mode. The Speller Pages spell checker needs to be able to run the shell_exec() PHP function, which is disabled in safe mode.
		+
		+	=== <span id="10">Firefox was not loading my toolbars if I used the default set, but it was working for basic.</span> ===
		+
		+	I found that there were certain buttons that caused problems Style, Font Format/Size/Face, Text Color/BGColor.
		+
		+	I finally figured out that this had to do with the mime type that my server was sending, so I added the following line to my .htaccess:
		+	<pre>
		+	AddType text/xml .xml
		+	</pre>
		+	This resolved the problem of displaying, but it turned out that was only part of the problem. It turned out that after I got the toolbars displayed, that FCKeditor never fully loaded - the progress bar was stuck almost all the way done and my memory usage was increasing slowly.
		+
		+	I resolved this problem with the following in my .htaccess file:
		+	<pre>
		+	<FilesMatch "\.html$">
		+	ForceType none
		+	</FilesMatch>
		+	<FilesMatch "\.htm$">
		+	ForceType none
		+	</FilesMatch>
		+	</pre>
		+	Like a lot of webmasters, I'm doing some funky stuff with mod_rewrite, parsing html as php, etc. It turned out that the things I was doing in my root directory were not compatible with FCKeditor.
		+
		+	In the end, this is what my /FCKeditor/.htaccess file looks like:
		+	<pre>
		+	AddType application/x-javascript .js
		+	AddType text/css .css
		+	AddType text/xml .xml
		+	<FilesMatch "\.html$">
