I am using apc module without problem (except annoyance with clearing caches-drush won't clear caches). But recently I migrated my modules from modules to modules/apc. This breaks the site with apc.
In settings php, I modified include line to reflect my new settings
$conf['cache_backends'] = 'sites/all/modules/contrib/apc/drupal_apc_cache.inc';
But still does not work (cleared caches, done registry rebuild).
If i comment out
#$conf['cache_class_cache'] = 'DrupalAPCCache';
#$conf['cache_class_cache_bootstrap'] = 'DrupalAPCCache';
site works again, but with no caching in effect.
Is there any help to this ?
