Hello,

In preparation to take our Moodle instance from 4.1 to 4.2 i'm trying to upgrade PHP on a Windows Server with IIS and MSSQL database. After changing the PHP version from 7.4 to 8.0, I get the following error:


Works fine when I revert. PHP error log looks ok. I have the MSSQL driver installed, that was showing a different error if that was missing. Any ideas?

So after countless troubleshooting for anyone else that might run into this. I had ODBC drivers 18 and 13 installed on the server. After uninstalling version 18 and only keeping 13 everything starting working again. What fun..
