I recently upgraded my boards from 7.2 to 7.5.4.2, and then ran the rebuild posts option. This worked fine for the most part, but really old posts (the board started on WWWThreads 3.5) have a lot of exposed HTML tags. If I edit them and change it to allow HTML and UBB code, it fixes the issue. However, it would be slightly time consuming to do that to 300k posts :-)
Digging into the database, I find POST_BODY has lots of stuff like this:
</font><blockquote><font class=&quo...
And then POST_DEFAULT_BODY has this:
</font><blockquote><font class="
If I edit a post and set the type to both ubb and HTML, POST_BODY ends up matching POST_DEFAULT_BODY with proper HTML.
Whats the best way to clean this up on a mass scale?
