PHP ErrorDocument mod_rewrite ProxyErrorOverride

@kivamp

The error is due to the following bug: https://bz.apache.org/bugzilla/show_bug.cgi?id=55415

You have two solutions:

• You simply comment the ErorDocument directive inside your .htaccess file and you live with the default error pages that you can customize through the panel interface
• You create a small listener file which will set the ProxyErrorOverride directive value to Off for the specified domain(s).

@kivamp

Without the ProxyErrorOverride directive set to On, any site which don't handle error documents through PHP will have no error document. For instance, if you reach an inexistent page, a blank page will be shown instead of the 404 error which is a very bad behavior for your visitors.

Note that this behavior only affects the apache PHP-FPM server implementation where the apache mod_proxy_fcgi is used... You could switch (not recommended) to fcgid to avoid such a behavior. In that case, the ProxyErrorOverride directive would be ignored in that context because fcgi don't use mod_proxy_fcgi.

Yesterday i upgraded I-MSCP from 1.3.0 to 1.3.5 and after i did apt-get upgrade on my debian too.

After all this, my domains get error 503.
I did not find any problem in the logs.

I was confused which upgrade was the problematic upgrade

I switched back to fcgi but fcgi on debian 8 has a bug too, so i switched back again to fpm and i tried to fix my problem.

I did not know untill now what was the problem, but the only solution was for me (not the best but worked) to restore /etc/apache2 from backup.

So thank you kivamp and Nuxwin for your help, now it is clear what happened
