Have you tried editing
\includes\acp\acp_forums.php and finding:
Code: Select all
if (utf8_strlen($forum_data['forum_desc']) > 4000)
then changing 4000 to whatever? If you're using MySQL, it appears that the
forum_desc column is limited to 65,536 bytes, so you'll be limited in how large you can set the field with the maximum depending on how large a UTF-8 character is. You should be safe going to 8000, at least, I think.
I haven't tried this, and can't guarantee there won't be ramifications to this change or that this is the only change necessary.
