The error i see sometimes is:
Whoops, looks like something went wrong. Check your librenms.log.

Check your log for more details. (librenms.log)

I just switched from apache to nginx, and the error only occur random which is quite odd. But the error posted from the librenms log is happening quite frequently.

Any assistance would be greatly appreciated.

Laravel 5.4 has a bug that makes it incompatible with PHP 7.3. Because we have to support PHP 5.6 right now we can’t use a newer version of Laravel.

Laravel caches pages so it doesn’t always hit the bug.

Okay, I’ll install php 7.1/7.2 besides 7.3 and see if I can get it to play nice.

Thanks for the information.

This should fix it:

cd vendor/laravel/framework
wget https://patch-diff.githubusercontent.com/raw/laravel/framework/pull/25193.diff
patch -p1 < 25193.diff

You should not be running older versions of LibreNMS any more. Update to 1.50.1 or the current master.
