Hi @Gbolly,

I see you’ve also posted this on another thread:

Please just post in one place; otherwise it clutters the forum.

Error 500 happens when server is not able to do what application asks it to do. Please inform your system administrator or hosting company about that.

QUICK FIX

sudo apt install php7.[version]-xml php-xml-parser php7.[version]-mysqli php7.[version]-mbstring && sudo service apache2 restart

Most installation guides forget this
