my system is Debian 9 Apache2 php-fpm
i am experiencing an error with one of the websites on my webserver.
I have tried adding an index.html file into the public_html directory (and disabling htaccess and wordpress index.php), however it appears to be trapping before the virtual host is serving the page.
i found the following in apache2 log for the virtual host where this is a problem.
It is also supposed to be the default domain for the host system ipaddress.

I am not sure what to do to fix this?
