This theme is not working on firefox! Its just black screen. How to fix it?

Hi, I have the same problem. I just bought Cubez Theme and all I see is a black screen, Mozilla and Chrome. Sometimes after 10 refreshes and back button I can see the page I'm building but already frustrated. :)

Thank you

Hi,

Sure, I sent it. Few more info about this problem. I re-started from scratch. I reinstalled WP and start working with Cubez. No problems for a while but when I added custom google fonts to Hover Box Settings>use custom fonts I got the black screen again. I deactivated it and it worked fine after. This morning, surprise, everything is black. 

PS I have no Widget space in Appearance. I don't know when that happened, on wp install or theme install.

Thank you

Update:

1. I replaced jquery 1.4. 2. with 3.2.1. It worked fine in Chrome and Firefox but not In Firefox developer. Sounds like a browser cache but I cleared it before and after going back to jquery 1.4.2.

2. I changed from PHP 5 to PHP 7

But it was a clean install. New WP and only the plugins incorporated in the Cubez theme.

jQuery v3.2.1 gives this error: TypeError: f.getClientRects is not a function (and some Cubez functions don't work)

jQuery v1.12.4 gives this error: Use of getPreventDefault() is deprecated.  Use defaultPrevented instead. (black screen in mozilla and after few f5 it works in Chrome)

Thank you

Update:

I uninstalled chrome and firefox, clear all residual data and seems to work after reinstall. The theme will probably be buggy on older browsers. I don't know that to think. I'll let you know if the problem reappears.

Cheers!
