Hallo all. I have an issue with ossn installation. I can install it with no problem on xamp on local machine, but when I try to install it on VPS I am always failing on third step with HTTP ERROR 500 or simply white screen.

However, I meet all requirements, and have no idea what can go wrong. Here is some warning and notices from error log:

This is log from last few times I tried to install.

I'll be very appreciate on any help or advice.
