Problem fonts and category

Since installing the 7.1 version of wordpress I have a problem, I can not change the font or the category that I have installed the template.

but any other template works perfectly.

I pulled this error in console:

Warning: Invalid argument supplied for foreach() in /home/blog/public_html/wp-content/themes/hottopix/admin/admin-interface.php on line 635

someone could give me a hand with this problem?

Best Regards
