Hi kobelka,
as already mentioned in your other thread, pls. consider not to use "
mpm-event", when you use PHP-FPM at your (sub)domain; use "
mpm-prefork" instead.
In addition, pls. always consider to post corresponding logs from BOTH webservers, when you use a combination of apache+nginx and don't forget to provide informations about your used PHP - handler and the content ( i.e.: wordpress, drupal, Joomla, other CMS, ... , magento, other shop-software, ... ), because such informations help as well to investigate a root cause.
Pls. note as well, that often enough, ".htaccess" - files are used, but nginx doesn't read these directives - you have to convert them into nginx - directives.
First suggestions:
- Pls. go to => Home > Tools & Settings > Apache Web Server and change the MPM - mode to "MPM-PREFORK"
- Pls. don't forget to enable the apache - module "proxy_html", "proxy_http" and "phpX.X", when you use a apache+nginx combination
- Pls. use the Plesk extension "htaccess to nginx". More informations can be found over a forum search, or by visiting: => htaccess to nginx - Plesk Extensions
- Pls. provide the informations about possible ".htaccess" - files
- Pls. provide informations about possible existent additional nginx directives
