Xenforo Installation fail E_Warning - ErrorException

[saforge]

I had Xenforo installed multiple times during the last years and it worked every time without any problems. But not this time:
After uploading the files, insert MySQL Data and start the installation it stops in the middle with this error. I tried it with the latest version 2.2.13 and the previous version, also uploaded the files again and so on - every time the same issue.

I'm not sure, if somethings is really missing or it's an PHP error? (and the appmusic file is there)
PHP version 8.2., the same with 8.1.9.

Have you tried with the 8.0.x line, which is actually the most recent officially supported verison?

 

[saforge]

Mmhh, yes, also with 8.0~ it's the same error.

Do you have any "custom" media BBCodes that you have created?

This will typically be because PHP doesn't have permission to write to the internal_data directory.
