I'm currently helping someone with their Wordpress site. They are running Wordpress 3.5.1. The problem is that I cannot drag and drop any widgets into their widget areas. I ran the Javascript console and found this error:
Uncaught TypeError: Object [object Object] has no method 'hoverIntent'
load-scripts.php?c=0&load%5B%5D=admin-bar,hoverIntent,common,jquery-ui-core,jquery-ui-widget,jquery…:3
I have moved the whole Wordpress site to a testing server. The problem is that this Wordpress site is running a custom theme, and a bunch of plugins (even som custom as well), so I guess updating the WordPress-script is not an option, if I don't want to mess up things completely.
I have deactivated and removed both the theme and all plugins, and the problem still persists. I can't understand why, as it should technically be a clean WordPress install.
Any suggestions would be appreciated though!
