Problem after activation

Hello,

I have problem after activation this plugin.
This error:
Warning: is_readable(): open_basedir restriction in effect. File(/home/users/smidl/smidl.online/sub/marmar/wp-content/plugins/awebooking/awebooking.php/languages/awebooking-cs_CZ.mo) is not within the allowed path(s): (/home/users/smidl/:/usr/share/pear/) in /home/users/smidl/smidl.online/sub/marmar/wp-includes/l10n.php on line 583

I don′t know, how to repair that.

Thanks
Jan
