Thank you for the fast response, Peter.
The plugin for the portfolio tracker was a custom development from cool plugins to add onto their coins market cap plugin and is called Cryptocurrency Portfolio Tracker. I do have both plugin zip files as well.
As for the live traffic monitoring, I can see the actions and they are showing successful on the live traffic. but the console is logging the 404 error to-
wp-json/wp/v2/crypto_portfolio?author=2&&status=private,publish:1
Failed to load resource: the server responded with a status of 404 ()
If I disable just the firewall, I am still greeted with the same error. It only goes fully away when I disable Wordfence.
Thank you again for all the assists on this. Please let me know if you need screen shots or access to the plugin zip file.
