'session.name' is not a valid sessions-related ini setting
Hello, since the update to PHP 8 I get this error message from my Omeka S. I have just updated the Omeka to the latest version. That didn’t fix the error either. I renamed all module folders on the server once, and named them correctly again. This did not help either. Does anyone know what the error is here?

Cause and Solution

This appears to occur with the combination of Omeka S version 3.x and PHP 8.1.

The issue here is PHP 8.1 specifically. You won't see it on 8.0 or older versions. An upcoming release of Omeka S will resolve this problem with PHP 8.1, but I don't have a date currently set on when that will release.

This information is from 2022, so for example, upgrading to a newer version of Omeka S as of 2024 can resolve this issue.

Summary

I hope this serves as a helpful reference for Omeka S operation.
