"http error 500"

I installed 2 days a go NC and it works until today.
I didn’t change a thing, but I’ll get the “HTTP ERROR 500”.
I only installed the calander/contacs/videochat app.
How can I fix it?

Go in your server and look if your Disk isn’t Full.
Try to restart your services : web (apache or Ngnix) database (Mysql or MariaDB or Postegrsql)
And look into your logs of your web service.

Paste the content of your logs here if it didn’t solved.

I reinstall Nextcloud and now it works.
I only receive a: "server repleid: Forbidden (Sabre/DAV/Exception/Forbidden"
How can I repair it?

Go in your data directory of nextcloud open the nextcloud.log and paste it here.
