Tinymce editor present, but buttons no longer visible

Just discover that if I disable the latest version of 6.x-2.x-dev (also downloaded and installed yesterday), the tinymce editor becomes visible if put a page in edit mode. I found out because there is in the logging a "page not found" error for "http://.../sites/all/modules/img_assist/drupalimage/"

Although /img_assist/drupalimage/ is on the server. How to solve this one?

It's not really a duplicate, because the forum referred to is D5.

I have D6 + wysiwyg 6.x-1.x-dev + tinymce_3_2_0_2.zip (well installed in \sites\all\modules\wysiwyg\tinymce) + img_assist 6.x-2.x-dev.

Can you tell me which patch I need to apply to make sure that the combination tinymce_3_2_0_2 and img_assist are working?

I also wonder whether it would not be better to asap make a released versioin of wysiwyg, tinymce and img_assist in which the latest big changes are all incorporated, because there is an urgent need for a working baseline. Right now, it is very hard to get a working baseline that includes tinymce3.x. For sure there are many many nice changes to come, but on the other hand, one can always improve code, endlessly...

@Sun: thank you, that is a clear answer, but I propose you indicate the current incompatibilities on the http://drupal.org/project/wysiwyg home page, to avoid that many people spend lots of time trying to make incompatible module combinations work together. You also want to avoid having to spend much time answering to the same issues being reported again and again.

Therefore, I propose that you extend the chapter "Supported editors/plugins" on the wysiwyg home page with the following remark (are you able to do that?):

/***********************************************************************************************************
Warning: if you need both img_assist AND TinyMCE, then do not yet use TinyMCE3.x, but stick to TinyMCE2.x.
=============================================================
For instance for Drupal6, the following combination of module versions has been tested and works:
- wysiwyg 6.x-1.x(-dev)
- tinyMCE 2.x
Do not take the end of life drupal tinymce, but download tinyMCE2.x from
http://sourceforge.net/project/showfiles.php?group_id=103281&package_id=...
To be installed in the wysiwyg folder (i.e. /sites/all/modules/wysiwyg/tinymce)
- img_assist 6.x-2.x(dev)
- views 6.x-2.0
- token 6.x-1.11
***********************************************************************************************************/

The same info can go in the readme files of both img_assist and wysiwyg.
Ideally, you make a release canditate of the two wysiwyg and img_assist modules, because the dev versions I tested are img_assist (2008-Okt-15) and wysiwyg (2008-Okt-17) are working today, but maybe not tomorrow any more....

The only question that I still have in this combination is how to find back the language package that goes along with TinyMCE2.x. I have the impression that the language package for TinyMCE3.x is not the right one...
