Dev site forwarding back to main

[mathforum]

Hi everyone,

I'm trying to update my dev site by clearing out the old one and making a new copy. I've followed the directions posted here and this process has worked before:

1) Turn off forum
2) Change forum folder and forum URL in AdminCP to point to dev site
3) Copy db
4) Change (2) back to main site values
5) Copy files over to dev site
6) Load db copy with new values
7) Change config.php file to new values

I've done all this but yet the dev site won't load and is immediately forwarding back to the main site. I do have DBseo installed but don't know how to account for this.

Any ideas?
