Hello. For some time now I have continued problems with changes made in the nginx directives in the options tab of the website. Every time I edit the vhost / website configuration and save it, I get an error email that Nginx was not able to restart. Even on very small changes that result in no big change, like changing the php version, I get the nginx restart error. When I diff the vhost and vhost.err files the only change might be the randomised string in the \.php$ location rule. I can delete the old .vhost file and rename .vhost.err to .vhost and Nginx -t will give no error. What is wrong here? Additionally, I noticed that the ##merge## Tags do not work in my Nginx directives, and if I put a location rule into the nginx directives it will not overwrite the rule of the vhost template file, but put a duplicated location rule in my .vhost file resulting in a real error. I'm really stuck here. Why is the merging of the nginx directives and the nginx restart not working properly? I use a conf-custom/nginx_vhost.conf.master maybe this is causing it. How can I debug this problem? Any way to get some debug output when ISPconfig tries to build my .vhost files? Update: I disabled my conf-custom/nginx_vhost.conf.master temporarily but the nginx restart issue still exists. The merging problem seems therefore related to my custom vhost template.
