Hello,
I'm still having problems when trying to install the quickstart of your templates.
Please note that I use the same provider for all my Joomla websites and I never met this issue with other quickstarts.
The installation fails after running the database setting page.
Here is a video of the setup, until it blocks: https://youtu.be/iq3dDaLYqGY

I just hope this can be resolved because I had the same problem with every quickstart I tried to use from Joomla51 (ticket also for Skylar and Sophia for the same reason).

Best regards
Maurizio
