Question AH01071 error.log

[bloosk]

Hello,

System is:
Ubuntu 16.04.4 LTS‬
Produkt Plesk Onyx
Version 17.8.11 Update #1,

its new system but with migration the customers from 17.5 and this problem is only with a php file with a html file
are all ok

on the old system if i called a file with www.domain.com/test.php and this file did not exist I got a 404 page from my personaly error docs.

on the new System i got only without html code, only "File not found."
with a hmtl for example test.html i got the 404 page

Please use this as starting point: How to enable custom error pages for domain in Plesk?

mostly the "ProxyErrorOverride on" does the trick and the custom error page should come up
