critical error when memcached enabled

please check with your provider , if this is running on Memcached or LSMCD ?

Hi,

thanks for the fast answer.

i have ask my hoster and he replied:

“As I have checked, it shows here that you are using the wordpress turbo plan and runs on Memcached”

bes tregards

Hi,

my hoster has answered me again.

Yes, both the Memcached extension and LSMCD cPanel feature are enabled on your cPanel but I think, right now you are not using Memcached on your LiteSpeed cache plugin as you have disabled the object cache feature on the LiteSpeed Cache plugin but the LS plugin is being handled by the LSMCD cPanel feature. You might be confused with Memcache and LSMCD, perhaps. Memcache is a PHP extension, you can check it through PHP Selector settings > Extension. While the LSMCD is a cPanel interface where you can manage a user to connect the LiteSpeed cache plugin for Memcached.

I have deactivated it only because then the critical error occurs.

Hi,

what if you add post_meta to do not cache group ?

best regards,

Hi qtwrk,

after exlude the post_meta i thought it worked because i could open some pages but then the critical error came again.

In the error log now see this:

please try add “user_meta” into no cache group as well , then purge object cache , see how it goes

Hello,

thanks for the answer. i tried and i also added usermeta to the do not cache group. Then I removed user_meta and usermeta from the global groups, saved, cleared the entire litespeed cache and browser cache but I still get a critical error. The error log says the following:

Hi,

just communicated with devs of LSCWP and LSMCD

there was some thing on the PHP extension that has issue when dealing with SASL authenticated data and leads to this error

unfortunately there is no fix to this , please turned off the object cache.

best regards,

Hi,

thank you for the answer, I know myself unfortunately not so well what are the data where do they come from woocommerce or from other plugins, themes or is it a matter of my hoster?

And would there be a chance that Redis works?

many greetings
Hasel

Hi,

yes, you can try Redis

Hi,

thanks i will ask my hoster.

best regards
Hasel
