I had a very similiar problem, removing the php.ini file resolved this issue for me, but your host may keep a php.ini file in a directory higher than you can access. hense the reason for the hosting provider question :)
Only thing I would suggest is setting "Loot Note Event Trigger" to on. And if you have ctra create a start raid then you don't need to use morgdkp's start raid anymore. ie "Create Start Raid" in options.
Thanks for the hard work Kardson.
Changed the Tutorial to include clicking the "Loot Note Event Trigger" Field
