The plug in Hummingbird is practically unusable. I get the white screen 20 - 30 times in a row, refreshing over and over. Finally the Asset Optimization screen pops up, and I make my changes and click Publish -- and white screen again. Have to start all over. I have been working for over 2 hours to simply publish changes and cache. I have tried with all plug ins deactivated. I even installed the standard Twenty Nineteen theme -- and it crashes just as badly. I am so frustrated, I want to uninstall all your software and never look back. Unfortunately, I haven't yet found a replacement for the features I need. I know lots of people have this problem, but I have yet to see any real support on the issue from you guys (other than it's somebody else's fault). Please advise.
