Yes the orange/pale blue skin you saw is the default SMF theme and I was working very late last night trying to iron out a few things, some of which required me switching between the default skin and our custom skin.
Although Ive been working on a 'test forum' for the past few weeks trying to make sure I could do as much as I could before performing the work on the live platform, there are still a few things that dont become apparent until they are applied on the live system.
So if you see the orang/pale blue skin, thats just me tweaking a few things on the core, and its only temporary whilst Im looking at some of the underlying stuff.
>> with the online help not working properly,
Yep the problem was with the core template. I am glad to say that should now fixed.
>> One minor point is that the logout and print (or mark read when viewing a topic) buttons dont show properly for me using FF V5.
This is most likely to be a caching problem... probably not helped by the fact that I have been switching between the 2 templates so many times.
I had the same problem myself this morning in both chrome + firefox 5 until I did a hard refresh using Ctrl + F5.
It seems to occur each time I upload a new CSS or switch templates... and its always the "last button" in the row that goes walkabout until you do a full refresh.
