I've seen closed issues about this (http://drupal.org/node/429744) for D6 but nothing for D7. I'm not really sure where to start.
I have a site that is constantly displaying the following system messages:
The content access permissions have not been properly rebuilt.
The content access permissions need to be rebuilt.
Every time I try to rebuild it fails with:
An AJAX HTTP request terminated abnormally. Debugging information follows. Path: /examplecom/batch?render=overlay&id=246&op=do StatusText: error ResponseText: ReadyState: 0
I've tried different browsers, cleared caches, etc. I even get the message with the Content Access module disabled. There's not a lot of content on the site so I doubt it's a memory issue. Can anyone give me some insight into what's going on here?
