While upgrading this site from 2.3x to 2.5.1, a message was displayed saying the database was out of date & needed to be upgraded. After finishing all upgrades and viewing the main site, it appears database tables were corrupted.
The contents of posts (154) were lost, category tagging appears to have been lost, and only 1 post title displays on the index page.
All post titles are visible in the manager interface, as are their respective URLs. When attempting to edit them, the editor window does not display.
Of course, I have a backup of the original database, made right before the upgrade. However, it seems differences in the databases are the 'base' of this problem - so any support is appreciated...
