Hi I am currently learning Metasploit & following the guide in the Offensive Security website. I have back track 4 (not R1) was able to fire up metasploit fine however when i tried to run the dradis server it gives me an error, I tried to looking for a solution but couldn't find any to fix it.

Below is the complete error message I got

I don't know what seems to be the problem but I just am not able to figure out, any help to fix this would be appreciated. Thanks in advance

Poltergeist,
I've got BT4-R2 and initially had a few issues with Dradis but not as bad as yours.  I ended up going to the dradis site and getting the latest version off there.

I had a few little issues/niggles during the install but now have the latest version running fine on both my PC and laptop.  etd, the guy who runs dradis is very helpful and fairly quick to respond to any questions or queries posted on the forums.
