    Hello,

    I have recently installed LiteSpeed Memcached (LSMCD), and enabled Object Cache.

    Everything seems to be working OK, but when checking error logs we discovered that Object Cache was generating PHP fatal errors.

    Because of this , we have currently disabled Object cache until we can resolve the issue.

    Report number: YAELUYJX

    Sample of PHP errors below (this is just one of many):

    [11-Oct-2021 13:55:42 UTC] PHP Warning: get_object_vars() expects parameter 1 to be object, array given in /public_html/wp-includes/class-wp-post.php on line 265

    Hi,

    Hi @qtwrk

    Not with regular memcached.

    Currently regular memcached has been disabled and not installed, only LiteSpeed Memcached (LSMCD) is enabled.

    Hi,

    if it works with normal memcached but not LSMCD , then it’s more likely LSMCD-side issue instead of plugin-side issue

    please create a ticket on LiteSpeed websites for LSMCD issue

    Best regards,
