From Joomla 2.5.8 forward, you might encounter a database problem which refers to the Assets Table when browsing some of the JomSocial pages.
Note: This is NOT a JomSocial-specific error as it does not use that table at all. It is very likely you will experience this error with other components too
- Joomla has already acknowledged and addressed this issue in an article covering the fix for it.
- Also, Joomla Forums has an answer for the issue.
