jond1 I installed the object-cache.php file in the wp-content director and removed redis plugin. which removed the redis object-cache.php drop in -- but I am unable to determine that the cache is working .. I install debug-bar and it shows now object-cache and I tried the admin tools dashboard and it was not able to detect any cache .. the redis-server is running and I can store keys and retrieve .. the permissions are correct on the pj-object -- Do you have any idea why it does not appear to be working ? Thank you
