I would definitely like to get this one answered as the project is somewhat urgent. Alex Rabe, are you out there?
I discovered that I had not checked the box next to “Enable flash slideshow” in the Gallery / Slideshow settings. It’s always the simple things.
That article did the trick! Once I changed the MySQL socket location and restarted Apache, everything was working properly again. Thanks!!!
The WordPress test sites were all working properly prior to upgrading.
After upgrading, MySQL wasn’t available at all and none of my sites loaded. I had to install the latest version of MySQL then copied the data folder from the old MySQL folder to the new MySQL folder. (Per instructions from the guy helping me out at Apple Discussions.)
