Hello- completely new to WP... using local machine as a testing server. I have set up Apache, php, MySQL on osX 10.8.x. WordPress is installed. I have just tried uploading a new theme and I'm being asked for my username and password. I'm assuming it is for the apache server? All I did was start apache... I didn't assign any credentials to the best of my knowledge. Is there a way I can determine what my username and password is? Thank you!
