Check for a `open_basedir` configuration
@aschempp may be the Contao Manager could check for an open_basedir configuration such as this? There are a few hosters out there that set the open_basedir to the document root by default. And I think Plesk does that by default too.

May be after the Contao Manager determined the installation directory, check it against the current open_basedir configuration and show an error with an explanation.
Plus a link to the performance section in the manual, explaining why this setting should not be used at all.
@fritzmg sorry I can't figure out what was meant here, do you still remember? What would the explanation be about? Be aware that there are no "warnings" in the system check, we can't "recommend" a performance setting (yet).
It needs to be an error anyway, not a warning. The original issue was about an open_basedir setting, where the path was pointing to the web/ sub folder of the Contao Installation. Some hosters use a variable for the open_basedir setting that represents the DocumentRoot of the vhost - which obviously will not work for applications that use a sub folder as its document root. The idea was to evaluate open_basedir, if set, and check for such a specific misconfiguration.
What would not work? If open_basedir points to foo/bar, I can always create foo/bar/web. And if the folder is /foo/bar/web, then Contao Manager will ask to create /foo/bar/web/example.com/web for you, because it can't write to /foo/bar (due to open_basedir).
