Newbie here who knows nothing really about CSS other than C&P'ing what others offer here.
I did go into CSS Editor to update 404 message - thought is was pretty straightforward. Clicked update and page seemed to freeze. Manually typed in web address and nothing but a blank page.
Have I broken my site? Can I restore it somehow?
I am using my laptop as my host via XAMPP. Tried going into XAMPP and pulling up site that way - nothing, same issue.
