I have installed the Quickstart Joomla 4 version of Gourmand to my server vis ftp, unzipped and run the installer but it runs in an endless loop! It will not install.

I deleted it!

I then installed the latest Joomla 4.0.3 files from joomla.org using the same credentials and the installation went perfectly.

I then installed three of your templates and made a demo page. ... Gourmand, Pitech and Helix Ultimate.

The default Joomla template works fine. Gourmand looks like it can work too Piteck shows just a blank page Helix shows an orange page saying "Sorry, there was a problem we could not recover from. The server returned a "500 - Whoops, looks like something went wrong."

So, I cannot use any of your templates as I cannot install the Gourmand Quickstart.

I tried using PHP 8.0 and PHP 7.4 login details are below, This is NOT a production site so please look at things, All templates are installed so you can try at your end. I really need to get a new site up ASAP ...
