Hi Mark,
I tried the install to 5.0.20 from the 3.9 version. I get stuck at 45% installation for way too long. I backed out of it and reinstalled the 3.9. This worked to get my blog back up. Anyways, I'm nervous to install the 5.0 again. Is there an update coming soon that will work better for installation? I have a few sites that I use the 3.9 on and I was going to test the 5.0 first on my main site...
