From Joomla 2.5.8 forward, you might encounter a database problem which refers to the assets table when you browse some of the JomSocial pages.
Note: This is NOT a JomSocial-specific error as we do not use that table at all.
- Joomla has already acknowledged and addressed this issue in an article documentation article covering the fix for it.
- Also, Joomla Forums has an answer for the issue.
