For some reason, when I open my modal I get an error page, but when I click on ←- previous then I’ll get the modal and I can close it.. Or is this an GitHub problem? (strange because on preview in Elements I get the same error) Got any suggestions?
I don’t know if this is the cause, but make sure the button you use for the modal window doesn’t already have an active link.
If there’s already a link, it can cause problems.
