Issue Nginx + Wordpress + Peepso - profile editing is not working

[Fant]

Hello,
I'm using nginx only configuration (php 7.2.16 FPM application served by nginx) with standard wordpress config "for one website". Peepso plugin is not working properly. Profile editing is completely not working, it's not loading (Update info button). Plugin author said it's problem with my Nginx configuration - index files or get params.
It should looks like this.

But it looks (/about it's not loading, it shows user profile):

Peepso got option to change url to seo friendly (it's removing ? from url so it looks: profile/admin/about), but it displays blank website.

Plugin is working on other nginx hosting without plesk but plesk is not working on standard nginx config with wordpress (of maybe someone got fix). There is fix for permalinks

if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?q=$1 last;
}

But it not fix problem with the plugin. Any suggestions?
