BOA Aegir Octopus, APC disabled: Module's php files seem to be cached, changes are not reflected. Why? I installed BOA on a VPS and everything seems quite alright except the fact that when I change a module's php file, the changes are not reflected in the website.

When I change something in drupal's index.php I can see the changes.

My first thought was APC which I disabled globally in php.ini for testing but that didn't help.

It looks like the file is never called, though I double checked that I'm working in the right directory and drupal setup.

Obviously I'm missing something and even Google didn't shed light no this.

Do you know what this could be?
Clearing Drupal cache may be not enough in this case. 

Since Redis is active by default, it may still cache some include paths, or there can be old paths still present in your system table, so you need to run the "Rebuild registry" task followed by "Flush all caches" task (the second is the same as running drush cc all on command line).   

If this still doesn't help, upgrade to latest BOA-2.0.6-dev (head), which includes recent APC 3.1.14 version to avoid this known APC bug.
