Problem with load matchs,teams,edit team not work

Hi.
I just buyed theme and i follow instructions.
I need help, can i get here ?
So many problems/bugs i find. First of them is:
1) When i create match and see “image vs image” i click there and it’s still only loading(broken)
2) When i going demo teams and select any of them, page only like loading never open.
3) When i try create team it’s white page only.
4) Images in icons are broken, not showing it’s just showing like broken image with “?”

I try with php 7.4 and 7.0
(It’s same)
I try full fresh reinstall full my cpanel
(It’s same)

What i can do this about ? Did i just lost 80$ ? It’s this theme full of bugs or only this ? Can we have better support here for fast contact, like discord server skywarrior ? Ty all
