Can't use File manager.

Hello,

after the Login the Interface show me:

( ! ) $DEFAULT_PATH must be a decendant of, or equal to, $ACCESS_ROOT
$ACCESS_ROOT = home/admin/web/xxx.de/public_html/test/
$DEFAULT_PATH = home/admin/web/xxx.de/public_html/test/

Warning: scandir(./home/admin/web/xxx.de/public_html/test/): failed to open dir: No such file or directory in /home/admin/web/xxx.de/public_html/test/index.php on line 2192

Warning: scandir(): (errno 2): No such file or directory in /home/admin/web/xxx.de/public_html/test/index.php on line 2192

Warning: Invalid argument supplied for foreach() in /home/admin/web/xxx.de/public_html/test/index.php on line 2102

I have php 7.0.30-0ubuntu0.16.04.1 with openbasedir on the default /home/admin/web/xxx.de/public_html.

Thanks,
FoxionPi
