On my site it looks like a file m=permission error on assets/plugins/tinymce3241/tinymce.linklist.php - for someone else’s reference.
I just ran into the same problem, after adding table support to TinyMCE. I’m not sure exactly what broke it, but I can narrow down the following:
I have two servers running. One is a Windows IIS server, one is XAMPP (Apache on Windows). The problem began on the Windows IIS server, after I played with TinyMCE for a few hours getting the table plugin to work. After that, the LinkList disappeared entirely (same problem as the original poster).
Since I figured I’ve still got one working server, I’d see what I could do to fix it. Here’s what I did:
1) Export ONLY modx_site_content from the problem site and import it into the good site.
RESULT: No change. Good site remains good.
2) Drop *all* MySQL tables from good site, do a full backup / import of *all* tables from the bad site.
RESULT: No change. Good site remains good.
Noticed at this point that the good site has the same problem with TinyMCE not wanting to support tables, as the bad site originally did. The plugin ("table") was listed in the "Custom plugins" list, and the buttons ("tablecontrols") listed in the "custom buttons" list, and the editor theme was set to "Custom."
3) Changed the TinyMCE Editor theme on the good site from "Custom" to "Advanced" to see if I could solve THAT problem...
4) Didn’t work (still no ’table’ buttons), so switched the theme back from "Advanced" to "Custom".
5) Now have the identical situation on both sites: TinyMCE does tables just fine, but now the LinkList has completely disappeared.
Note that I didn’t change anything in TinyMCE’s PHP files, and everything worked fine until the switch of the themes. "advlink" is still listed as a "Custom plugin"... just doesn’t seem to be registering for some reason.
Any ideas?
[UPDATE]
Reinstalling TinyMCE appears to have mostly resolved the issue. The LinkList looks very weird now (not the nice ’tree-like’ structure there was before), but I think I can fix that with some other topics here. At least the LinkList is back AND I have my ’tables’ buttons.
[UPDATE #2]
Completely fixed after replacing the tinymce.linklist.php with the alternate code for sorted lists, here in the forum!
