If you encounter the message "Could not Save" from the Chrome/Edge Evercontact plugin there is a couple things to verify first:
1/ Logout/Login from the plugin to restore any permissions to your Contacts that can be missing
2/ Sign In on https://evercontact.com with your Gmail credentials and verify that you currently have a valid Evercontact license (billing section). The Chrome plugin requires at least an Essential license to work. You can discover our different license plans at this address https://evercontact.com/pricing
