disabling session by memcached resolved
how to enable it again?
Hi @alexrus76g
You can enable memcache again by following the below steps :
'session' => [ 'save' => 'files' ],
'session' => [ 'save' => 'memcached', 'save_path' => '127.0.0.1:11211' // your ip and port number of memcached installed ],
For more details refer this link - https://www.a2hosting.in/kb/installable-applications/optimization-and-configuration/magento1/configu...
Hope it helps !
Hi @alexrus76g
For this issue , i would suggest you to look into this link - https://devdocs.magento.com/guides/v2.2/install-gde/trouble/php/tshoot_session.html
Explained well to work around on the same issue !
Hope it helps !
I'm also experiencing the same problem. Does anyone have a solution?
I can confirm the site is working when switched back to saving sessions via files.
I tested and memcached is working (with a standalone php script.)
Hi, the support for memcache was dropped in magento 2.3.0.
I have created plugin which allows use of memcache for session.
Documentation is available here: https://connect20.aveo-trade.cz/docs/user-guide-memcached-2.3.0.pdf
Consider switching to the Magento recommended session storage Redis ->
https://devdocs.magento.com/guides/v2.3/config-guide/redis/redis-session.html
Very simple to setup and works just as good if not better than Memcache.
Confirm. I have same error in 2.3.1
