It's me again, and I have the following issue: Some menu items are redirecting to 404, but only when I access my website through a cellphone, and they don't redirect if I I'm on the homepage. For instance, if I click on any sub menu item of Inscrições and then click on the menu item Inscrições again, it's going to redirect to 404. I have no idea how to solve this problem, and it's really bugging because nowadays most people access the internet through their cellphones.
Do you have different menus for your desktop / mobile?
Can you reproduce this behavior with the "Inspect" function of Google Chrome in the Mobile Phone mode? Right click on your site, choose "Inspect", choose "Toggle device toolbar Ctrl+Shift+M"
