We did have a new release of the site on Monday which introduced expanded features for Free members - unlimited listing of online recipes by adding blogs/websites, adding online recipes from the Library and adding recipes using the Bookmarklet. In addition we have added advertising for Free members and anyone not signed-in.
I thought that maybe the advertising feature required a sign-in but I haven't needed to sign-in myself. I se Chrome so I am wondering whether there is an issue with just IE and Safari. Have any other members had this issue and what browser do you use? It helps if I can go back to our developers with specifics on which browsers are experiencing the issue.
