i sent the other site to you so you could see what the cmu site was like before i started making changes to it.
i've got the root as / because i publish pages outside my www directory...and my weburl like it is so i can browse all the folders in the site. both the "connections" and the "test" folders are outside the www directory.
the behavior extension set up an mysqli connection automatically (and is able to connect to it); however, when i try to run a test on the query is when i get the error. is there any other information i can get to you that may help?
