[Plugin: W3 Total Cache] Memcache Not Detected

So it was detected before, and now it’s not detected anymore. I’m running Apache with Zend Opcache and PHP-memcache

The compatability check says it’s not found.

php -r 'phpinfo();' | grep -i 'memca'
memcache
memcache support => enabled
memcache.allow_failover => 1 => 1
memcache.chunk_size => 8192 => 8192
memcache.default_port => 11211 => 11211
memcache.default_timeout_ms => 1000 => 1000
memcache.hash_function => crc32 => crc32
memcache.hash_strategy => standard => standard
memcache.max_failover_attempts => 20 => 20
Registered save handlers => files user memcache

I can seee memcached running in my htop viewer as well.

I removed all my plugins and reinstalled w3-total-cache. It then said there was a critical error with memcached. I renamed the config file in the wp-content/cache/w3-total-cache/master.php. I don’t see it anymore though, that folder has disappeared. I’d like to get memcache back online, so let me know if anything else could be helpful. Thanks!
