If you come across this error:
AccelerateWP: End user can't activate "Object Cache Module" - Unknown custom object cache plugin is already enabled
it is probably caused because of leftover files that conflict with the AccelerateWP suite.
This might be because the cache plugin has recently been removed/disabled.
To resolve this, ensure that no "object-cache.php" files are located within the WordPress wp-content directory.
If there are any, simply remove/rename them.
