[Assigned] 503 error (ATE)

Hello,

Do you have any particular cache setup on the server-side?

I'm seeing a few blocked jobs from WPML and it seems it's happening because of cache. the debug log is full of issues like this:

[13-Aug-2025 12:02:35 UTC] objectcache.notice: The cache key `af87fac234541eef540df0a1d1241ca7:0.40683600 1755073231` is incompatible with prefetching and the group `creatives` should be added to the list of non-prefetchable groups. For more information see: <em><u>hidden link</u></em>

Interestingly they started more or less yesterday i think it was at night. Now it seems something is failing with the cache, since as you can see it's not really working with a lot of keys. WPML ask for that info, gets the keys which are not compatible and fails. as a result it's blocking you on our end because of errors.

I suspect it happened because of the timeouts and if that's the case a simple flush of that object cache would probably do (I guess you turned on Redis, right? i remember it was disabled before).

Would you be able to do that so I can see if that helps?

Redis shouldn't cause issues if it's correctly configured but for now, try to flush it and let's see if the errors continue, ok? if you have a developer, ask them to take a look at the debug.log and check if it's worth adding some keys to the exception list 🙂

We, on our part are aware of some possible object cache issue which should be fixed soon, but they are different from the ones you're currently experiencing which is hitting WPML as well but indirectly.

Ok, I can see the site is not being blocked anymore which is good. I'm running a few tests but so far most of the translations are already done. I'll check the arabic ones, because since they were in the trash, they still appeared as translated and the system ignored them.

I'm resending them at the moment. I'll come back with more info soon.
