Currently with Safari and Chrome Links are working ( i assume you have the intro-feature disabled ). It will be hard to identify whats wrong while everything is working unfortunately.
Also just to be sure:
Wordpress, Lay Theme & Laytheme's Addons are all up to date ?
Any custom CSS or JS that may interfere is temporarily removed.
Any third-party plugins are de-activated to see if this resolves the issue.
Talk soon @neirynckwout & have a wonderful day 🏖
