This may be caused by any ad blocking software you are running in your web browser. There may be an icon in the upper-right corner of the browser that says something about ad blocking when you hover over it. If you will turn the blocker off for our site (the secondstep.org domain), the page should stop reloading/refreshing.
If you cannot change your ad blocker's settings, you may need to contact your school or district's IT team for assistance.
