I'm in the Verify Configuration step of the install, setting the database parameters. When configuration builder tries to connect to the database I get the error: I'm pretty sure the mysql parameters are correct because they're the same ones as in my VB3 config.php. I tried connecting to existing and non-existing databases. What I SUSPECT is happening is that Xenforo is trying to do something not supported by my PHP configuration. Trying to execute a program that doesn't exist, or something like that. VB3 works fine, though. Unfortunately I can't figure out how to get any more detail than this error message. Does anyone have any suggestions? Thanks.
