You can live chat with me on the #nextcloud-dev irc channel

[thenamelessthing]

As mentionned in the https://help.nextcloud.com/t/forms-internal-server-error/74440/13

I can comment the line #277 of the file /var/www/nextcloud/apps/forms/lib/Controller/PageController.php

but it is the right thing to do?

[jotoeri]

Thank you for reporting this. The bug itself has been tackled already, so with the next release it will be solved.
Your given solution out of the forum is good, that should work and won't break any functionality.
If you want, you can alternatively install current beta of Forms v2.0. Detailed steps for this are given in #349. However, keep in mind it's not released yet, so can contain other bugs.

And just for the next time - Please search in the old issues, if your problem has been reported yet. This makes life much easier for us to support you. ;)

Greets,
Jonas
