I can go back to that conversation and everything looks fina until i send another message. When i do that then again - after about half minut - same thing: reload and “The conversation does not exist”

I don’t have any errors in logs but i do have errors in JS console

At last case closed… At least for me…

It is something with caching. Distributed caching to be more specific. I’v turn it off and everything looks to be fine,

I had caching configured in my config file like this:

  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.distributed' => '\\OC\\Memcache\\Memcached',
  'memcache.locking' => '\\OC\\Memcache\\Memcached',

now i have:

  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.locking' => '\\OC\\Memcache\\Memcached',

Maybe Memcached on my server can’t handle distributed caching? Or maybe its a bug? I don’t know. Fortunately i don’t need it so for me it’s the end of the topic.
