Support » Installing WordPress » 500 error on install page

  • Hello, i have a strange problem. When i open my site to complete WordPress install on web interface, it errors with code 500 with PHP 8.1. If I switch to 8.0, i can install just fine, then i switch PHP back to 8.1 with no problems. What caused the issue? Thanks.

  • Hi @twilyhoney,

    It’s very hard to know since the issue didn’t happen again, and therefore we don’t have the exact step-by-step to reproduce it.


    This is typically caused by a PHP function included in the PHP8.0 version but changed/fixed in 8.1, if no files/dir ownership or permissions were changed in between.
    If you do not specically need 8.0 you are safe to go with 8.1, however for a Production site that may be a courageous choice 🙂
