I encountered the following issue after my wordpress site has been tampered with and I subsequently upgraded to 2.3.3, restoring content from a backup (all of this makes it relatively hard to track down what specifically caused the issue:
In the Write new Post Panel of the Administration Panel the 'Browse All' selection doesn't show me all images, but just those uploaded after the upgrade.
- no thumbnails or placeholder at all show up, as if the database doesn't know about the images
- the images show up fine in all posts on the site itself, old and new
- I tried to search the mysql database for differences which cause the issue, but with no result. Entries were existing for both the older and newer uploads. I am not very skilled with mysql though. If it helps I can post the relevant table data.
Thank you for your help - Thomas
