Thank you, @siniplyrathemes, for your quick reply and helpful response.
Your second piece of advice worked renaming the plugin folder. For some reason, the 3rd tech guy renamed the plugins folder causing the plugin issue.
The white screen is still there, however. When the plugins are deleted, it’s there. When they are installed but deactivated, it’s still there.
Like I said, it’s just the homepage “www.thebackpackartist.com” but all other pages and posts appear, like “www.thebackpackartist.com/about” or “www.thebackpackartist.com/travel”.
