Having messed up my dev site (running on Win 7 using Acquia Dev Desktop), I restored a backup I took a few hours ago with the Backup & Migrate module. Now when I click the local site name in Acquia Dev Desktop I get a Choose Language message from Drupal instead of my site. I'm certain I had this problem a few months ago, but I apparently did not make good notes because I don't know where I found the instructions to fix this problem. My guess is that the $database parameters are wrong in settings.php or maybe there's some other problem.
Help is appreciated!
