WordPress Widget dropdown arrows are not working
Here is a curious thing.
I have WordPress in a few subdomains. And all but one worked fine.
I went to edit a sidebar widget (as you do) and the drop down arrows were not working… This is quite serious as how on earth do you get to the content? For many manually editing the Database is not for the fainthearted! Well in actual fact for the VAST majority of people there is a simple solution before you begin to start disabling plugins and switching your theme/s.
