When I upgraded to the first alpha I got a 500 error. I cleared browser cache and then studio cache. That did the trick. When I went to view profile pages I got a blank page. I figured out that it was a 3rd party app from MS Solutions. Disabled it and the page showed up. Upgraded to alpha 2 and bugs were fixed and site loads up. Would be nice to know how many sites that are still having the errors are on their own server vs UNA Cloud.
