The only two things that could be wrong server-side are:
[list=1]
- Someone's editted the PHP of the showthread.php so that when it calls the buttons, if the post[userid] is kode's it excludes the Profile button. But that'd've have to be deliberate.
- Someone screwed kode and put him in some reject usergroup. That's the only way (methinks) you can exclude people from viewing profiles in a non-hacked vB.
The other possibilites are there's something on kode's system stopping it showing. Pop-up and banner blockers sometimes screw things up. Or if he's running through a proxy that sometimes makes things hit-or-miss.
I'd say disable all anti-crap programs and ctrl-F5.
If it IS something server-side, the only things I can suggest are reverting the postbit template in the AdminCP (which, depending on how Styxx did the avatar-code, might kill the avatars temporarily); And checking what kode's usergroup is.
