Thanks Seveneth. I just ran into the same problem. I added the line as you recommended, cleaned out a few “Array”s that were in the database (in the posts and options tables, if I recall), and the problem cleared up.
This was WordPress 2.2.1 (installed through Fantastico) (as reported in the page’s meta tag), PHP 4.3.11, and MySQL 4.0.27-standard (both as reported by CPanel).
I was able to ‘fix’ this problem by removing the query string from the script include in wp-admin/admin-header.php
that is, I changed:
<script type="text/javascript" src="../wp-includes/js/tinymce/tiny_mce_gzip.php?ver=20051211"></script>
to
<script type="text/javascript" src="../wp-includes/js/tinymce/tiny_mce_gzip.php"></script>
(around line 50)
I don’t know if there are any detrimental effects from this, but it does appear to have worked….
