After adding Twitter widget all following widgets disappear, code unexpectedly ends
After uploading and activating the theme I entered my Twitter API info in the Theme Options, then went into Customize and added the Tweets widget. I entered my Twitter username and saved.
Once I refreshed the page the Tweets widget did not show and all other widgets below it also disappeared. Using the F12 tools in IE I can see the page code is now cut off at the Tweets widget DIV tag.
The 'Widgets' section is also now missing from the Customize menu.
If I remove the Tweets widget all the other widgets reappear and the code returns to normal. The widgets section in the Customize menu is still missing however.
I can repeat the issue by just adding the Tweets widget and entering my username again. Just having a username present in the Tweets widget seems to be breaking the rest of the page.
I have tried removing and reinstalling the theme from the zip but all my settings persisted. Not sure how to do a complete clean uninstall.
