Hi there to everybody,
it is great to be back on deck and start a new year working with Dotnetnuke.
I am having a problem with one of my websites running Dotnetnuke version 6.2.5 in regards to the main menu. For some reason several of the links to different pages on my website are not working.
These links are under a main subject heading for example:

Articles of Interest (Main Menu)(works ok)
Page1 (works ok)
Page 2 (it is several of these sub links that do not
Page 3 respond to being clicked on)
Page 4 (works ok)

I have used firebug to inspect the elements in question and it shows that the links are pointing to the right locations for each file.
I was wondering whether anybody had come across this before.

Any help would be greatly appreciated
in anticipation
regards
Trevor
