Number of visits not showing

I get the following error:

___________________________________________________________________________
Warning: Invalid argument supplied for foreach() in /home/user/public_html/wp-content/plugins/wp-statistics/includes/log/last-visitor.php on line 53
Toggle panel: Recent Visitor Statistics
Recent Visitor Statistics

he following error was encountered while using the WP_Statistics_Pagination class:

The value set for total entries is invalid:
___________________________________________________________________________

This is when I go to the menu item ‘visitors’.
If I go to the ‘Overview’ tab, my hits are showing, but not then number of visits.

Is there some kind of javascript conflict with an other plugin?

I am using buddypress and rtmedia. I have read on some blogs that rtmedia seems to make more conflicts with other all kinds of plugin scripts. But with buddypress you’re kind of depending on rtmedia.
