Support » Plugin: Redis Object Cache » After upgrading to 1.5, can’t flush

  • Resolved gridpanebobby


    Hey there!

    We’re seeing a problem with customers who have upgraded to 1.5. On 1.4, caching could flush without a problem, but once customers upgrade to 1.5, it breaks.

    Object cache could not be flushed.

    I’m trying to figure out what changed that is not allowing it to work now.

  • Here’s the diagnostic. Changing the timeouts didn’t help either. What did help though was disabling selective flush. What changed from 1.4 to 1.5 in regards to selective flush?

    Do you Redis log show any errors?

    This might be fixed with this, not entirely sure.

    This was due to this issue:

    Which has been fixed by a merge in github here I believe:

    Looking forward to update.
