Hi,
yesterday i finally got the time to upgrade my iRedAdmin-Pro from 2.9 to the latest.
Got a problem (i was getting a internal server error). While looking to debug the issue today I noticed teh new 3.8 version, so I tried that one, but i get the same error, here are the relevant logs from apache.

Any suggestion on how i could further debug it?
Is it possible that the issue is caused by jumping from 2.9?
Thank you.
