I found the solution:
Turn off wp debug. Open wp-config.php and set WP_Debug to false.
With help with this link “https://codex.wordpress.org/Debugging_in_WordPress”.
For anyone else who might be searching with the same problem.
Thank you so much for your response!
I tried that earlier and it seemed to have some sort of connection with wpbakery page builder. I would disable it and the notice would disappear but so would all of my page content since I built it through that plugin. I went through and had my company purchase the actual plugin instead of the free version so I could update the plugin but the notice still remains.
That’s what led me to believe it could be an issue with wordpress itself but I’m not sure. When I switch it to the original Twenty Nineteen theme, the error didn’t show.
So maybe I should take this problem to the wpbakery forum instead?
