Hi @alexrus76g

 

You can enable memcache again by following the below steps : 

 

  1. Using your preferred text editor, navigate to the directory where you installed Magento, and then open the app/etc/env.php file.
  2. Locate the following section in the env.php file:
    'session' => [
        'save' => 'files'
      ],
  3. Modify this section as follows:
    'session' => [
        'save' => 'memcached',
        'save_path' => '127.0.0.1:11211' // your ip and port number of memcached installed
      ],
  4. Save your changes to the env.php file. Memcached is now enabled.

Re: memcached related error after upgrade to 2.3 from 2.2.6

That is what i did by going back to saving sessions in file, but its not a
workaround, rather this is reverting to default magento behavour. What im
trying to get soution for is how to start using memcached again

Re: memcached related error after upgrade to 2.3 from 2.2.6

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.

Re: memcached related error after upgrade to 2.3 from 2.2.6

I tested and memcached is working (with a standalone php script.)

Re: memcached related error after upgrade to 2.3 from 2.2.6

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

Re: memcached related error after upgrade to 2.3 from 2.2.6

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.
