permissions

In Drupal 7, there is a *very tricky* problem you might fall upon at some point. We did and because it's not *really* a Drupal bug (although it could be considered as a usability bug), it's worth writing down. The problem is simple: one admin (Joe) and two editors (Sam and Max) edit a website. They all create their own content of the type "artist". They all have permissions to "Create artist", "Edit own artist", "Edit all artist" and "Delete artist". Also, the "artist" content type has a text body which can use the "Pure text" format, the "Filtered HTML" format and the "Full HTML".

There is a common problem appearing when installing a new Chamilo portal that I have seen a lot recently, so I thought I'd share the details here.

The problem

When installing Chamilo on a cPanel-kind-of-hosting, it might happen that you complete the installation, but when you want to enter a newly-created course, an ugly error appears.
