I'm upgrading from 0.8.2 to 0.8.5. I'm trying to follow the upgrade instructions but I don't get very far. I've ftp'd the files to a roundcubeupgrade directory. I cd'd to the roundcubeupgrade directory and issued the ./bin/installto.sh ./roundcube-0.8.2 and get the error message:
/usr/bin/env: php: No such file or directory
I've used putty to ssh to the VPS and I'm logged on as root. I searched the forum but don't find a report for this problem.
