Running on PHP 5.2, WP 2.8.1 - I did the automatic upgrade for my blog, then the next thing I know file permissions are goofed up on the server, nothing appears as it should, and now, after the server guys got it all "straightened out", TinyMCE no longer appears. Mind you, I can see it to administer it, but when I go to write a post, no TinyMCE. Any clues?
