What is the solution and how do we implement it for various hacks?

How did you do the install? Did you remove all files before uploading RC3? Also it COULD be a permission problem, maybe permissions have changed.

I just uploaded the files and set it to overwrite all files. The same way I have always done it. Never had any problems with the navgroups disappearing anywhere from Beta 4 - RC2. What kind of permission problem?:ermm:

EDIT: Okay. I think I have fixed the problem. Well, I dont think I have, I know I have, but I'm not sure why it was a problem in the first place :ermm:

Okay, so I was playing around the with nav XML files and by changing <navgroups product="vBulletin"> to <navgroups product="vbulletin"> (ie. the "b" in vBulletin to lower case) the navgroups re-appeared.

vBulletin != vbulletin :)
It must be vbulletin.

(Think I did that wrong in my How-To ... checking)

Yes Productname is case-sensitive.

But it worked in RC1 and RC2 no problems.. That's what confused me... Doesn't matter anyway :)

RC1 and RC2 didn't care if the Product was present or not.

That explains it then ;) Thanks for the help guys :)

Hmm i think i am the one to blame for this then. I made a bugreport that when a product was disabled, the menu options still showing.
