Hello!
I got a problem with TinyMCE WordPress: "someone" turn it to html mode and I hadn't ability to switch it off - back to visual editor.
This "someone" was NextGen Gallery plugin.
Deactivation of it made TinyMCE capable of functioning.
Is it a common trouble?
I never heard , please delete the cache folder in wp-content/uploads/js_cache and try it again.
ME too! same problem here! new install wordpress 2.5.1, NextGen Gallery make TinyMCE html editor break.
Have you done my instruction ? Which browser do you use ?
There is no such folder in wp-content/uploads/
I USE IE 6
same problem when use FireFox, browser error show:
illegal character
wp-includes/js/tinymce/tiny_mce_config.php?ver=20080415
error: tinyMCE is not defined
file: wp-admin/js/editor.js?ver=20080325
line: 82
Reupload all files again, maybe some of them are broken. Here I have no problem with ff2/ie7... and clear the browser cache.
Thanks, Alexrabe, it really was about deleting '...wp-content/uploads/js_cache', but before it I had to execute this:
Edit the following file: yoursite/wp-includes/js/tinymce/tiny_mce_config.php
First, comment out (by instering // before the code) while ( @ob_end_clean() ); at around line 13. It is immediately preceded by // Discard any buffers
Then, search for "compress" until you find 'compress' => true and change the "true" to "false.
It turns out, that in my situation there were no problems with the respectable NextGen. It was just a coincidence...
