I also have this problem. I previously had “AddThis Social Sign In” but have since removed that plugin. I’ve created a new Twitter app, deleted the “new Twitter users” but WSL doesn’t seem to recognize the email associated with the email registered to the Twitter account.
I’m on WP 4 and WSL 2.2.2. WSL works seamlessly with Facebook and Google logins though. Thanks!
Just installed. Facebook & Google logins worked smoothly.
I fixed the Twitter error by deleting the white pace as mentioned above. Great find joivmaco. Thanks!
