CSV-export not working

[uschmi]

When clicking on CSV -> Export to CSV in a list in our frontend there appears no popup / no export is available. In out backend this works fine.
Anyone any suggestions about the reason / how to solve this?

We are using Joomla 3.9.18 + modified Protostar template + fabrikar from Github about 3 weeks old...

Did you try with original Protostar?
JS errors in your browser console?
3rd party plugins/components overriding standard JS in the frontend?

Thanks troester for your reply. It was something with JS from another plugin...
