Hello, I updated from 6.6.4.4 to 7.0.2 and am receiving an error message about a critical error on the page where external users can add events via the form.

I customized the forms a few months ago when I started Events Manager.

If I go back to 6.6.4.4, the error disappears.

Can you tell me what I can do?

Hello Marcus,

This detailed error message appears when I update to this version. I don’t receive any error messages with the older version.

Hello,

The error you’re providing indicates you have a custom template within the /wp-content/plugin-templates/events-manager/ folder, which is /wp-content/plugin-templates/events-manager/forms/event/when-with-recurring.php

Unfortunately, due to the major changes and improvements in how our recurrences form works and the UI enhancements in v7, old template overrides like yours will likely need an overhaul too. It’s likely you’ve got a better chance figuring out what you changed from v6.6.4 by comparing templates with that one, and then transitioning those changes over into the new form.

Now, events-manager/templates/forms/event/when-with-recurring.php is not actually doing anything anymore, because we’ve unified the date selection forms between recurring/repeating/normal events it loads the events-manager/templates/forms/event/when.php file.

I recommend you revisit your changes and also evaluate whether your changes are necessary, and if so, can then be added some other way, i.e. via CSS, JS, or using our PHP hooks (actions/filters).

Hope that helps!

Hello, thanks for the explanation. It partially worked. 🙂

Now, however, the recurring events are displayed as a 404 page. The date is added to the permalink….
…/events/weekly-market-in-hohenau-2025-07-17-2025-07-24-2025-07-31

Why? How can I fix this, please?
