Chamilo throws error during installation when hyphen (-) is present on DB-name

Hi,

I would like to install Chamilo (https://11.chamilo.org/documentation/installation_guide.html) on WordPress.
But during installation I got an error cause my hosting automatically concats and ID on the DB name that the Chamilo **cannot** understand hyphen.

i.e.

chamilo_db-143545

so the part: -143545

causes a problem during installation.

How to make a workaround for this?

Br,
John
