Edited templates in /events-manager/templates/ not showing on site

did you put them in a folder called plugins?
If you would access them from the browser it would look something like this:
https://www.[siteurl.com]/wp-content/themes/[themename]/plugins/events-manager/templates/category-single.php (this is an example offcourse)

Indeed I did, yes. I also tried it in the theme root in case that made a difference, neither seemed to work.

If you check the settings page of the events-manager plugin, and then the tab called pages, and check (for example) the Event list/archives section of the page. Is the option ‘no’ selected for “Overwrite with format”? (It could be that it’s named a bit different, My wordpress is fully translated into another language through a plugin, and it’s also translated some parts of the events-manager plugin). The explanation for the option I mean is “By using formats, you can control how your evenementen are displayed from within the Events Manager Formatting tab above without having to edit your theme files.”

If the option ‘no’ is selected you can’t use the templates. Change it to yes and if correct the templates you created should be used then.

I have ‘yes’ selected, but nothing. Only works for single-event.php – I can’t figure it out.

This is driving me mad!!

I’m sorry but I haven’t got a clue where the problem could be then.

Last thing I thought of, but it’s a quite obvious one, but the “overwrite with format” option is used several times for the different sections of the Page Tab in the Settings area. Are you sure they’re all on ‘yes’?

Could you post links to the page and the template otherwise?

If it’s not showing, 99% chance is you haven’t pasted it in the right place.

However, are you saying the edited file single-event.php does get overriden by your template and not category-list.php?

If so, then you need override with fomratting set to yes in Pages > Events Categories as @the0and1 correctly predicted.
