open_basedir settings
I noticed it I turn on the Plesk default setting for open_basedir in the PHP settings that I get the static content again, just no dynamic content or that's how it appears.
If I turn open_basedir to none, then I get just the PHP errors.
I left it to open_basedir "default" at the moment so you can see the three errors it throws showing an open_basedir error along with function errors.
