Hi the @Gerhard — Does your host offer PHP for your account? If so, what version are you running? You’ll need v5.6 at a minimum.
If it doesn’t offer PHP or they don’t have it installed you will not be able to use Alloy as it is a requirement.
If you do have PHP running on your server and it is v5.6 or newer, then I’ll move to my next question — did you follow through the tutorial videos step-by-step when you setup Alloy? If not I would suggest going through the tutorial videos, following along with them as you set it up.
