Using Agile child theme, somewhere along the way, the sticky menu has started misbehaving. Now it only shows up once, the first time I scroll down the page. If I scroll back up, and then try and scroll down again, the sticky menu won’t show up anymore.
Codewise, the header (id:header) will only change its class to “sticky” on the first scroll down. When I scroll back up, the class changes to “” and stays that way no matter how much I scroll down after that.
You need to set the URL for the top navigation menu item – ERP-PALVELUT which is causing a script error in the frontend which is leading to many other issues including the sticky one. The URL for a menu item is required and wordpress generally insists on this.
