I suggest you have a look at your webserver logs. It is probably a webserver configuration problem, not a Roundcube problem, and the server logs may give you clues about why permission is being denied. It could be as simple as the files to be served are not world-readable, or more subtle, like you're missing a needed web server access rule to explicitly allow access or script execution, or although there is access to the scripts, there isn't access to php.

Hello,

Newbie question: After following the instructions on the website to install Roundcube (unpack into /var/www/html/, setup MySQL database, etc.), I encountered a Forbidden error when trying to access the installer page.

How do I troubleshoot this issue?

Thank you very much.
