Interesting....is this website using k2?  

 

This site is in Polish and has that dreaded 500 error.  Not on the whole page but in the top l/r slider titled 'WYBIERZ DZIAŁ'.  All of the links are 500 pages.

Dave, I got your gtalk im.  Sorry I didn't reply, when you sent it I was in the middle of a week of nightmares. Although I didn't quite understand exactly what you were explaining, I'm glad you got things worked out.

 

ps. Anyone got any idea what template they're using on that page?
