Error when posting a new thread

[selfobsessed]

Gives me this error when someone posts -


Warning: Invalid argument supplied for foreach() in [path]/dbtech/vbactivity/includes/libs/activity.php on line 411

On refreshing the page, the post is successfully made.

Any ideas ?

Can you go into the AdminCP and run the "Repair Cache" thing there? That should sort out those errors
