A most common Installation Error in SuiteCRM Cloud-based implementations is file/directory chmod permissions.
It would advantageous to have what I will refer to as a Preinstallation or PostInstallation Validation Tool of some sort to circumnavigate or avoid these items. Unfortunately, at lot of time/effort is spent reiterating what the default directory permissions should be.
This could be extended (PHP,MYSQL) and/or the entire setup environment for either pre/post installation.
A common scenario is the installation goes through successfully without the proper permissions applied; and users get module/functionality error messages at the Human Interface Level without realizing root casuality is a permissions issue. Would go a long way to increase user acceptance and general goodwill.
