We are having some major troubles with our website. Basically the homepage works fine when you get onto the site, but when you try and click anything past that the website just black screens and there is a small white cross in the top right like some kind of popup window has opened but you can’t click that either.
Could really do with some help, thank you very much.
Our website so you can see if the problem happens to you too (you have to click something, ANYTHING)
