I had someone view my home page and give me some suggestions. They gave me a code which I put in. I saved and opened a new window to check it out...well my home page is blank. I went to go back to remove it and now there is no save or reset...what ever button next to save. I tried another section like discount coupon and the buttons were there. I logged off and logged back in and no buttons...I now have a blank page....what did I do and how do I fix it?
