Yes the message is coming back continuously, I also have a Connection refused message :

[12-Jul-2024 14:38:34 UTC] PHP Warning:  unserialize(): Error at offset 0 of 15 bytes in /xxxxx/xxxxx/domains/xxxxx/public_html/wp-content/plugins/bulletproof-security/bulletproof-security.php on line 237

Litespeed Cache was causing the problem. Redis was being used instead of Memcache. Changed Litespeed Cache setting and Port (11211) for object cache.

Response from another person experiencing this PHP error:

Hi,

Thank you for your prompt response.  Your comment about server-side caching helped.

While neither the memcache nor redis extensions were activated in cPanel I noticed for some unknown reason that the Object Cache setting in the LiteSpeed Cache plugin was ON (the extensions status said disabled).

I turned the Object Cache to OFF and have not had the above PHP error notice since; hopefully that’s it.

Thank you for your time.
