Vvveb cms problems with php / database

Hello, please help me with vvveb instalation on xampp or any other server.

The editor works, but when i’m installing cms from vvveb.com i got stupid mysql / php error.

here is topis on github repo but its pretty much dead project…

The error messages basically tell you what’s wrong.
If you don’t understand them, you should probably start learning the basics of PHP.

And if it’s a dead project, you should probably find an alternative.

i’m not a programmer. I’m just looking for help only with this one problem
