We have a lot of show posts settings, but when I try to edit them, I often see this error:
WARNING: invalid form submit detected (atw_posts_save_filter_opts). Probably caused by session time-out, or, rarely, a failed security check. Please contact WeaverTheme.com if you continue to receive this message.
This is on a news website with a lot of posts, inkfreenews.com
UPDATE: When I refreshed the page, I noticed it was loading for a very long time. On chrome, I saw a spinning icon on the tab. I waited until that finished whatever it was doing (2minutes or more), and then made the adjustment to the settings and saved without getting the error message.
