When I create a new Content Type I am getting the following random issues:
1. When I go back to Content Types list (/admin/structure/types) the newly created content type is not in the list
2. I get random "Page not found" error massages when trying to edit or delete fields on newly created Content Types or when trying to delete the Content Type itself
3. I can delete Content Types, then visit other admin pages and when returning to the Content Types list page, the types I just deleted appear in the list again.
3. When I delete a Content Type and then try and create it again with the same name I am getting an error that the name is already in use.
These issues appear to be random and don't occur with any observable consistency.
I am using the current dev version of APC (7.x-1.0-beta4+8-dev) and drupal version 7.23. The same issues also occurred when using version 7.x-1.0-beta4.
My config settings in setting.php are:
* Add APC Caching.
$conf['cache_backends'] = 'sites/all/modules/apc/drupal_apc_cache.inc';
$conf['cache_class_cache'] = 'DrupalAPCCache';
$conf['cache_class_cache_bootstrap'] = 'DrupalAPCCache';
