I got this message:
BackUpWordPress is almost ready. The backups directory can't be created because your wp-content directory isn't writable, run chown qud34Q:g37131 /var/www/g37131/laser-therapie.info/HTML/wp-content or chmod 777 /var/www/g37131/laser-therapie.info/HTML/wp-content or create the folder yourself.
but backups folder exist with chmod 777.
I am also using Bullet Proof Security 46.8
P.S.: I downgrad 1.6.4 working fine with no chmod 777 error.
