APCu Object Cache causing Cron/Post Editor Issues

    Hello,

    I’m experiencing persistent issues when using APCu for Object Cache:

    – Scheduled posts fail to publish.

    – Post editor behaves erratically (e.g., drafts not saving).

    I have confirmed APCu is active from my host (apc.shm_size=128M, apc.ttl=7200). Also i have disabled Database Cache (no conflicts).

    Is this a known issue? – Are there recommended settings for APCu + W3TC?

    Hello @haonas

    Thank you for reaching out and I am happy to help!
    Do you have any other caching engine that you can switch to that is memory-based like Redis or Memcached?
    Can you please try switching to Disk temporarily if you do not have any other memory based caching method available so we can quickly check if the issue is related to the APCu?

    Thanks!

    Thank you for the reply Marko.

    no unfortunately redis or memcache are not available im on a shared hosting plan where my only option for objects caching is apcu.

    My current apcu settings are:

    apc.shm_size: 128M

    apc.ttl: 7200

    I had disk as option recently and it was working without any issues but as you can figure i had to switch to avoid the large files.

    Is there any solution or my only option is to disable object cache?

    Regards

    Hello,

    i applied your suggestion and the issue remains.

    While composing a new post i was asked to login more than 5 times and i couldn’t upload image.

    After turning the object cache off everything worked as expected.

    Hello @haonas

    Thank you for your feedback.
    Are you using any other uptimization plugin or any other DB optimziation solution?
    Any chance you could share the website URL?

    Thanks!

    I don’t use any other optimization plugin, nor for the database. I have exactly the same issue on two different websites. Unfortunately, I cannot share the URLs publicly.
