Unable to open /var/www/admin/lang/

[Zegnåt]

Maybe using RewriteBase / to define absolute path in .htaccess would do the trick ?

Not here. This path is used by the PHP includes in the GetSimple core and those are not affected by .HTACCESS-files.

Regardless of the whole matter, who on the earth puts webservices in admin’s directory? :/

That’s the question, you would expect the root to be /var/www/test.site.com/. And because that’s the expected output we never thought about making the function work with anything else.
