Hi, I am seeing a little bug recently when trying to access my widgets pages on my local wordpress websites.
Instead of seeing the drag and drop widget page, i am just getting a source code page for the page as seen in the screenshot.
It is happening in a few of my local wordpress sites, and i am not sure what the problem is. I disable a plugin, and then try and it shows up, but then next time you goto the widgets page it does the same thing, so disable another plugin, and works one time. I'm not sure what the problem is, and searched a bit to see if anyone else had this problem but no joy. I am using Wamp Version 2.0, wordpress 3.2.1. I have the exact replica of the websites live on the net, obviously use localhost for testing, everything is fine live.
