when I run the installer, I had forgotten to set the permissions on one of my configure.php files. No problem, I just zipped into ftp and changed it. ON the installer screen however it had options to re-check and the others were grayed out. There was a huge red warning about hitting upgrade instead of install above that. So I hit the recheck, everything was fine, scroll down and now no warning displayed and only option is install or recheck. there isn't even a button for upgrade.

do I install it? What did I do??

ETA: I read the docs, and what it said about not connecting to my database. Check my configure.php settings. I'm not sure what else that meant both mine are at 0777 right now for upgrading.
