Hallo!

I am a beginner in the field of website development and I have the following problem.
I have already created a folder in xampp > htdogs and I have made inside to the folder extract the quick start folder of the tamplate.

However, when I write in browser localhost/folder I take the following:

Warning: count(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\hellas2018\installation\angie\models\steps.php on line 389

What can I do to solve the problem?

Best regards,
Eftimis
