Plugins not working (javascript not executed, language not loaded?) since 2.2.8

After upgrading one site from Revolution 2.1.5 to 2.2.8 (because of the security issues), I had to upgrade tinymce too (from 4.3.0 to 4.3.3).

Since the update I can not change links, images, colors, etc. All the pop-up windows show, but completely gray. Using the chrome-debugger, I remove the 'display: none' from the body class and see the layout but with all language-tags instead of actual labels (e.g.: {#style_dlg.text_font} ).
I've got no javascript errors as far as I can see.

I've already cleared cache (several times), reinstalled, uninstalled and installed, tinyMCE. Without luck! I also searched this form, but no solution yet...

Any help is really appreciated!

Thanks in advance,

Maurice.

Really strange, using IE9 the pop-ups show up the way they should. It looks likt Chrome is blocking something for this specific domain? That's a first as before the update to revo 2.2.8 and tinyMCE 4.3.3 it was working... And other sites with 2.2.8 and 4.3.3 work too....

I'll keep digging...

Did you clear your browsers cache and MODX's? Try opening the site in an incognito window in chrome see if there's any changes.

When you say you cleared the cache, do you mean you manually deleted all of the folders under core/cache/?

Had te same problem. I had multiple languages in my modx site and the tinymce could not find the correct language file. Because of that, he showed no file browser in the TinyMCE. Went into the tinymce plugin code (in the manager) en edited the if / else check on line 61. Removed this if/else check and had the language file set to english and tada, the file browser is working and tinymce is fully functional again!
