"No Thread specified" - Not your traditional newb problem either.

[KevinAce]

Hey,

I did a fair amount of searching and was unable to find any information on anybody else having this problem. Basically, I have a link on my site directly to a thread on my forum:

http://www.site.com/forums/showthread.php?t=45

Occasionally, I will be forwarded to http://www.site.com/forums/showthread.php and greeted with:
"No Thread specified. If you followed a valid link, please notify the administrator"

If I go back & click the link again, everything works great. I've made no major coding mods / additions to the forum itself. The only "mod" I've done is added aMember.com "vBulletin" plug (essentially registers people for vBulletin when they signup through my aMember software). Perhaps this could be to blame?

Is there any error logs I could check that might shed some light on this? Any incite would be greatly appreciated.

Thanks,
Kevin
