I've taken my widgets and moved them to the Inactive Widgets box on the Dashboard. I check the blog to verify that they're no longer visible, check! I return to the blog sometime later and all of the inactive widgets have returned to the sidebar. At first I thought the behavior was due to removing all of the widgets, so I created a couple of new, placeholder widgets. Again, the same experience; that is, they disappear only until my next visit to the blog. I've repeated this sequence three times now, so it's definitely an issue and not a quirk.
Any advice for keeping those widgets in the inactive state?
The blog I need help with is pannonica.wordpress.com.
