Well, I finally got my problems solved. It wasn't Drupal, it wasn't my web host, it wasn't even my pc, really. It was my firewall! Thank goodness that an update to CA Security Center made it easier to find the setting I needed to change. Now everything is working just fine.
I got all my Drupal updates made, and I'll finish updating all my photos this week. Which is just in time, because in just two weeks, I'll be in Huntsville, Alabama at Con*Stellation XXVIII: Vulpecula.
And then, I'll barely be home for a week, then Jeff and I are off to Collinsville, IL for Archon 33!
