Error System plugin

Hello PKP. I’m a journal manager at ISI Padangpanjang. Indonesia. at My University I use OJS 2 for all Journals. but there are 9 journals using OJS 2 which have problem in System Plugin
and can not access to custom block manager and side bar settings and others . because the plugin system has sent:

This page is not working journal.isi-padangpanjang.ac.id is currently unable to handle this request.
HTTP ERROR 500

does pkp have a solution for this problem?

does PKP has a service for this problem?

https://journal.isi-padangpanjang.ac.id/index.php

Salam Didin

HTTP Error 500 will be easier to solve by evaluating the error on your web server log.
It will be very helpful for the forum to help you if you can copy-paste the error 500 that will show the root issue for your problem.
