I have been installing multiple instances of Big Brother on Centos 3.5 at one of my current job sites. After everything has been downloaded, installed, patched, updated, dependencies resolved and many coffees later I hit the url and get this error:
“You don’t have permission to access /bb on this server”

A problem I have had each time, and I keep forgetting which directory permissions are causing the problem.

The solution is to make sure the big brother root directory has execute and read access for the webserver. So if you installed at /home/bb/bb1.9e-btf, you need to change the permissions for the /home/bb directory.

chmod u+xr /home/bb
