Thanks Marko. Somehow restarting my. ubuntu server resolved everything . Is there any explanation of that?
I can go to this link thou
https://www.mysite.ai/wp-admin/admin.php?page=w3tc_general&_wpnonce=4fe805632f
and it shows me this
he following memcached servers are not responding or not running:
- Database Cache: 127.0.0.1:11211.
- Object Cache: 127.0.0.1:11211.
- Page Cache: 127.0.0.1:11211.
This message will automatically disappear once the issue is resolved.
However, memcached is installed on my machine. and I can telnet and. can see using ss command
