I just upgraded to a new version of WordPress (2.3.3) from a really old one (2.0.x). Mostly because the old one was giving me issues embedding a flash app for Duels Defense. It’s mostly been good. I only have two issues:
- It randomly inserted all over my old posts. What’s up with that? Can anyone tell me how to get rid of this because it makes all my old posts look like crap and it would take forever to go back and edit them.
- The new interface isn’t quite as good as the old one for writing posts. They should check out confluence – it’s awesome. (It’s an enterprise wiki – we use for all our internal stuff at Challenge Games.)
So my apologizes for the weird stuff in the old posts. Although if people are reading them they are probably deep linked or Google search results anyway, so they won’t see this. Ah well.
Two suggestions for getting rid of (#2 worked for me):
#1) In wp-config.php try disabling UTF-8 or the other suggestions in this post: http://wordpress.org/support/topic/strange-character-appearances-in-old-posts-after-db-restore
#2) Use the WordPress Search and Replace plugin ( http://wordpress.org/extend/plugins/search-and-replace/ ) to replace all of the  with an empty string in the content table.
