Site blank on desktop, but not on mobile

Hi,

I installed the Easy Blogging plugin and the Ultimate Branding plugin, and was also modifying the functions.php file.

Now, my site shows up blank on desktops, but not on mobiles.

I have tried deactivating both plugins and the problem still exists.

I also tried deleting the functions.php file and uploading a backup copy and it didn't work.

What can I do?

Thanks!
