I'm getting an odd error using this module. When I'm logged in as an authenticated user and I go to a node that I've published there are usually three tabs (view, edit, and publish). When I first load the page the edit tab is there, but after a second or two it disappears/collapses. When I disable the module, this problem goes away.
Besides this, the module is working correctly for authenticated users and at the bottom of my page source I can see that authcache is working.
Any ideas anyone? I'm stuck on this one...
