Hello, I hope I didn't miss this question somewhere in the forum, because I always look there first (usually with success!)

I have recently updated the items in my Featured Products sidebox, and now that I want to add some new ones, I keep getting a 504 gateway time-out that says "The gateway did not receive a timely response from the upstream server or application".

I am able to add new products through the zen admin anywhere else as far as I can see, and I have no idea what the problem is, or what to do to fix it.

Any help would be greatly appreciated. Using 1.3.9h, website is www.cornerhardware.com.

Thanks!

EDIT: I just realized I probably put this in the wrong category...I'm sure it's not the end of the world though :)
