Please post your issues one at a time with new threads. Include links to the pages that don't work and steps to reproduce. Long threads with lots of issues are confusing to reply to and probably confusing for you to follow the replies. Also, please don't use the private area for information that isn't private. Leave your questions and descriptions in the public area so others with the same questions can find their answers.
