Unwanted extra pages in my "WebQuest Friend" MySite
My "WebQuest Friend" site I have created appears to be gathering pages that I have not created. This is within the "Should Australia have a War Memorial for Aboriginal Australians" section of my site. The unwanted pages include what looks like 2 folders and a page. Their titles are "MATX", "Childhood Obesity", and "9th Grade". I have tried removing them but whenever I click on either the Edit or Delete symbols, a blank page loads. I've tried it numerous times and the same thing keeps happening. How can I get rid of these?
Any help would be greatly appreciated.
