Problem using xerte on XAMPP for MAC user

Hello!
I've installed the last version of xampp and download the last version of xerte. I can access to my localhost/xertetoolkits_3.8/
but when I try to edit a project, a new windows appears and nothing happens (I attach a screenshot)
What's going on?
Thank you in advance!

Hi
from memory with XAMP on Mac you have to explicitly enable write permission where you need them and not just Xerte any application. Try a general search for making directories writeable on xampp for Mac.

Thank you Ronm,
I've change the permission to "read & write" for all the xampp folder but I'm still having the same problem
Any other options?

Could you please check the php error log and/or appache2 error log.

You are probably missing a php extension (like xml).

Thank you for your feedback Tom!
I decided to re-install XAMPP but not the VM version that I already had, but this one 7.4.6, and now its works
