I've had a nightmare the past few days (and I have other things I am supposed to be doing). I am running Moodle 1.6. My host upgraded php from 5.1.2 to 5.2.3. On 5.1.2 everything worked fine. Because of a known bug that has been mentioned here in the forums, forum posting stopped working in 5.2.3. This I could fix with an upgrade to Moodle 1.6.5 but I didn't have time to do an upgrade, so I asked to be moved to another machine. I was moved to a machine running 5.1.6. Now, the html editor is not loading at all. I had some customizations to my editor but I removed those to isolate the problem but even with the standard editor it is not working.
So my host made some changes, and got TinyMCE working, but I want the standard editor.
I've seen the posts about the intermittent html editor problems some people have been having but I don't think that is the case.
You seem to have so many problems with all editors that I would take a backup of all customized files and replace ALL files of moodle with new moodle 1.6.5+ package. Visit http://yoursite/admin/ and moodle should be ok again. Check also settings from
Administration -> Appearance -> HTML Editor -> Use HTML Editor
and from user profile:
When editing text: Use HTML editor
If everything works again as normal try to move customized files back later.
The problems followed me to 1.6.5 and back to the original server. I have been poking around and came across this tool. Running it on the listed files, the only problem I find is the following. Does anyone understand what this means?:

I should add that running debugging shows no errors on the page where the editor is supposed to load.Here is the html for where the editor is supposed to load:
<script type="text/javascript" src="http://www.glyphdoctors.com/lib/editor/htmlarea/htmlarea.php?id=8"></script> <script type="text/javascript" src="http://www.glyphdoctors.com/lib/editor/htmlarea/lang/en.php"></script> <textarea id="edit-message" name="message" rows="25" cols="65"></textarea>
I just wanted to add that something that jumps out at me in this is the fact that it inserts the course number (?id=8) at the end of the htmlarea.php url. I don't see this with the other editors, nor do I see this in the code for the pages here at moodle.org where the editor is working. Is there any significance in that?
It inserts the course number to give teachers and admins access to the files area for that specific course. That way you can use the htmlarea editor to select images you uploaded, etc... (and I may be wrong but I think that's why you don't see it logged in as a student on moodle.org)
Can't help you with your html editor problem, but I have similar problems with the html editor loading only half the time. Sofar none of the solutions have helped.
It simply means that file lib/filterlib.php is not found (it may be missing or not found from the place where it should be). At the beginning of weblib.php
require_once("$CFG->libdir/filterlib.php"); is serching filterlib.php.
require_once("$CFG->libdir/filterlib.php"); is serching filterlib.php.
It is there though-that's the odd thing.
