Xibo 1.8.13 Dashboard Error

I always liked version 1.8.13 of Xibo. Today I went to install it and I managed to install it without problems, but when performing the Login the Panel has some problem that I can’t identify. It simply does not appear on the side menu and when I try to perform some functions such as changing the password, for example, it displays the message:
App message
Oops! An error has occurred, please contact support.

How can I fix this version I downloaded directly from Gihub.

Have you looked at the logs page? what’s there?

Another thing you have to pay attention to is the PHP version.
Version 1.8 uses PHP 5.6 if I’m not mistaken.

I came back after a while.
Just giving feedback, I believe the problem was caused by a server error. I fixed it after restarting the server.
