Hello

I just buy a Joomla template, and I'm unable to run the .JPA installation correctly. At least CSS and images are not loaded.
What is the PHP version required please ?
Even with 8.0 and 7.4, it generates this page at the end of the process : http://www.black-coffee.fr/goelette/index.php
Do you have any idea the mistake I make ? Maybe is it due to my hosting ?
Thanks by advance,
