Server Specs:
DigitalOcean
Ubuntu 16.04
php7
apache2
MariaDB
I haven't tested how much time it takes yet, but after, let's say, an hour of being logged in to my board with no activity (going from page to page) my Flarum board gives a 500 server error after I try to log out/navigate to new page/do any activity.
After I refresh the main page, everything acts as expected, and I am able to log out or navigate to a new page.
Has anyone else experienced this?
