Hello Ofi Khan,

have you been able to find anything about the error? Do you need some other information from me?

Thanks and best regards

Please take a full site backup with Akeeba Backup in ZIP format and share here. Follow this tutorial

This works ONLY on the home page. As soon as you select another menu item it does not work anymore. I suspect a javascript error... Can you please help me?

Hi Steve. It is unlikely that this is javascript error. Otherwise, it would not work on the home page too. Maybe I'm wrong, but the frequent reason for this problem is that any element overlaps the button and does not allow click on it.

Or duplication of Header/ Menu position (for example, to display only on mobile), frequent user error.

Browser dev tools can help in determining the reasons.

I am not an employee of support, so I can’t access your site to check. Therefore, only assumptions and tips :)

I have found the error. Jquery is not loaded.
