Thank you for the great tips! Caching helped a lot. As far as identifying the root cause, I’m still at square zero. If a plugin is the problem, wouldn’t the server memory or CPU utilization be high? I monitor memory and CPU of the server in real time and it’s consistently low. I might be just the last guy in the door. Not sure how I got deprioritized and no help from BlueHost either.
To update, my issue was caused by one of the WordPress plugins (Media Library Folders) because there was a configuration problem with folders. To find the issue, I open the page in debug mode (F12) and watched the error messages in the Console window. After resetting the folders using the Media Library Folders Reset plugin, the issue went away.
