Using "upload package file" or "install from folder" on a clean new Joomla 3.5.1 installation without any other extension I get this error :
Cannot open mysql://XXX:YYY@localhost/XXX?new_link=true: DB Error: extension not found
Tried 4.7.7 and for testing even CiviCRM 4.6.16 LTS -> same error

Maybe someone has an idea what I could do to get it installed, thanks
