Error

I’m using a Dashboard Widget Sidebar plugin which lets you add widgets to the dashboard.

When I add these widgets, I get this error message “Warning: strip_tags() expects parameter 1 to be string, object given in /home/fbceugene/webapps/fbceugene/wp-content/plugins/network-latest-posts/network-latest-posts.php on line 246”

Does anyone have a fix?
