@mariofucile I encountered the same “Forbidden…” problem so you are not alone. I am attempting to install SuiteCRM-8.0.3.zip on FreeBSD v13 with PHP 8.0.15, Apache 2.4.52 and MariaDb 10.5.13, and using the recommended vhost definition in the installation instructions.
Since our hosting systems are different, I created a new topic with my own hosting information.
