Getting blank screen at domain.com/admin when installing I'm trying to install Craft for the first time, I've used Ben Croker's requirements check and everything passes, and I'm pretty sure everything else is set up properly, but when I access domain.com/admin to run the install, I just get a blank screen - no errors, warnings or messages.

I've tried installing in a subdomain (my preference) as well as in the root, with the craft dir both above and below the root, but get the same result no matter what the config.

I've checked the logs (craft.log) and it gets this far (see below). There is no phperrors.log file. Does anyone have any ideas where I should check next?

I'm documenting this here in case it helps someone else. My white screen during installation was caused by a missing comma between array items in my general.php and db.php config files. Once I added it, the install page loaded correctly.
