I added a page viewer web part to one of my site pages. However, it was behaving in a strange way. When you would go to the site page, it would show you it for a short moment, then it would take you to the actual URL of what you put in the page viewer. I deleted the web part from the page. You can't see it on the page now, but it's behaving as if it is still there. It keeps rerouting me to the URL of what I wanted in the page viewer.
