Editing events in Events app results in 500 error

Hello Perchers,

I tried updating an event on a client’s site that I set up a couple of months ago using the Events app.

Problem

When I view the events list in Perch Runway and click on an event to edit it, I get a 500 error. The front end is working fine, I just get the errors in the Perch back end and cannot edit or add new events anymore.

What I tried

Seeing another forum thread (https://forum.grabaperch.com/forum/04-11-2016-events-app-admin-fatal-php-error) and my PHP error (see below) mentioning repeaters, I noticed I use repeaters because my events sometimes have multiple dates and I need a repeater in addition to the standard event date. Removing the repeaters in the template does not solve the problem, same HTTP 500 error.

According to my git commits, the file "PerchFieldTypes.class.php" that is mentioned in the PHP error log was changed in June when I updated Perch to 2.8.29. I haven’t edited events since then, so this change might be the source of the problem and it slipped my attention.

Kind regards Jannis

PHP error log

(Note: The folder "typo3" is a remnant of an old Typo3 installation that has been removed, but the domain still points to that folder.)
