How to make and edit your private server [BASIC & NOOB FRIENDLY]

when I try to register a new account it shows me this:
prntscr . com/1xyd0f
what do I do?


and when I go to a portal it gives me black screen and runs the same things in the left screen
prntscr . com/1xyfre

I still can not make myself admin! Please help! I do not know my mysql user and password I really need help

^^ That bump...

umm error retrying?

I have an issue. I am using Sequel Pro instead of Heidisql, and I changed my rank to 5 (which is supposed to be admin). Whenever I press play and then choose my character, it just stays the black screen that says nexus, and has my character on it.

Can someone help me how do i make accounts
