"Invalid website basedir." error in config
After ISPconfig 3.1dev install completed, with no clients or sites yet, only server-name, when under System > Server Config > Web I try to set the Website basedir to something more logical for my situation (a bunch of migrated websites), whatever I fill in, at Save it keeps on failing with;
"1. Invalid website basedir."
Perhaps also tell the user WHY it's invalid? I'm at a loss here. I tried "/srv", /www and many others on Ubuntu 16.04 with nginx only (no apache, luckily). Please advice, and let's just assume I can't live with the apache structure of "/var/www" etc.
TIA
