Hi, At the server level, I added the following entry into the Apache-style settings: php_value open_basedir "$VH_ROOT/public:$VH_ROOT/includes" The resulting open_basedir value though held the server's prefix not the $VH_ROOT. If I add this entry at the template level, it works as expected - not tested on the individual host level, but I'm assuming it works correctly there. I've not tested any other uses of $VH_ROOT at the server level. I'm guessing this isn't the intended usage. Version : LSWS Standard 4.0.13 Thanks.
