What happened?​

Since an update circa January 1, 2025, the meeting list page on the EDA website is not displaying to end users and is giving slightly different errors on different browsers as follows:

Safari TypeError: undefined is not an object (evaluating 'e.trim') Firefox TypeError: e is undefined Chrome TypeError: Cannot read properties of undefined (reading 'trim')

When we go to check meetings as WP admin, everything looks ok until you go to add or edit a meeting:

Unfortunately, I have not been able to reproduce this in a development environment. Below is a stack trace from SiteGround, our Wordpress servicer.

We're still using v3.16.6 because updates trigger the bug, but otherwise:

WordPress version 6.8 Active theme: Enfold (version 5.1.2) PHP version 8.2.28

What browsers are you seeing the problem on?​

Safari, Chrome, Firefox

The answer​

thanks @gkovats 🙌

@gobborg it will be in the next release, but fyi we have a lot of changes on main that we're working on, so a release is not imminent - my recommendation for now is to edit your site's variables.php to make the same change in this PR
