Troubleshooting

I've made changes manually and now I can't git pull... what now?

$ git fetch --all
$ git reset --hard HEAD~
$ git pull

How do I find out if my permissions are right?

$ namei -om /www/phparcade/

I'm on Digital Ocean and SMTP isn't working

You need to set your precedence, since Digital Ocean doesn't support IPv6 SMTP. Here are the steps for CentOS7 (but should be very similar for other *nix systems)

Fedora

$ cp /usr/share/doc/glibc-common/gai.conf /etc/gai.conf
echo "precedence ::ffff:0:0/96   100" >> /etc/gai.conf

"Feature XYZ isn't working!" or "I get an error when I do this!"

Post a bug report and I'll do my best to help.
