title: sharepoint showing error after uploading a new webpart
body: <p>I am new to Sharepoint and was playing with the webparts. I downloaded a zip file called LyteBoxForSharePoint and uploaded the webpart using add a web part function. Now I am getting errors. The good thing is, that it's only my dept page. The bad thing is I have no clue what happened. All other pages beside the dept landing page is working. So, I am guessing it's only the landing page that has the issue. Is there a way to find out what code was added or to revert to old code. The error I get is the following, and it keeps on changing every time I refresh the page.</p>
