AVS 404 not found issue

[shemalehunters]

so I have installed AVS on my server and it's such a headache here is what I installed:
PHP 7.3 with PHP CLI 7.3 and also PHP-FPM 7.3 and GD2 and Curl
I have Nginx running and the problem is that the admin page works fine and the homepage too but all the other pages are messed up and show error 404
this is how my nginx error log looks like

Try to post this on stackoverflow, there are many experts there who know how to solve this type of problems

check cache folder permissions.

its a php notice with the script, not an error.

they probably did not add in a check if the index is set.
