Brett -
When I login to the original site it takes me to the original site.
When I put everything on the test site I updated the values to reflect the test domain. The test site works ok and all the links & nav point to the correct place on the test site.
On the original site it the nav directs me to the test site almost as if they are linked in some way. If I type in the correct page like site.com/ page it get a 404 error like it doesn't exist. I also noticed that if I activate or deactivate a plugin on the test site it changes them on the other site. These sites are on completely different hosts with completely different domain names.
