Help break this code

The following is encrypted using a Caesar box code. Supposedly you just group the letters in fives and then read vertically. I tried it and it does not work. Anyone have any help for me. The twenty five letters are:

WTRGOWRTDTWOLOCDBANOOENDM

WTRGO
WRTDT
WOLOC
DBANO
OENDM

Seems to say: www.robertlang.com

You mean www.robertlangdon.com right?

Yep, sorry.

Thanks, that was really quick. I had it right before my eyes and couldn’t see it.

WTRGO
