Thanks for the feedback. I've got every url using the full
http://www.dayone.co.uk/.. or
https://www.dayone.co.uk/.. command paths. WHat is strange is that when the menu is fully https:// it happily allows users to get to the none http:// pages directed to by the menu system. Unfortunately the menu then will not display the sub menu.
I really should have mentioned in my original message that the error is that the submenu will not display in the main display frame if the menu frame and the main display frame are not both using either ssl or non-ssl pages. As soon as you mix a frame with ssl and non-ssl pages the menu stops showing the submenu.
I'm wandering if the mm_navframe.js file needs additional programming to cater for the mix. I'm just amazed if that is the case as that would make me the first to mention the issue. Which is not likely, or is it?
I'm happy to test any ideas anyone has.
