Widget page not working

I cannot open any of my widgets or drag them on the widget page, it’s like the page is frozen. I also am not able to change the font coloring of the widget titles in my sidebar from using the options on the WPZoom page under Theme options and then under the styling menu. Changing every other option in this menu has worked but not the sidebar widgets. The footer widget titles have changed color tho.

Thanks for your help.
