Loading into a Mac

Recently upgraded to OJS 3.1 and when I try to see the manuscripts in my portable Mac it only showed the loading symbol, but it never loads. I don’t have that problem with the other Mac that I have at home. Any suggestions on how to fix the problem?

Here is the message in my browser:
