WP-SpamShield changes a default behavior of WordPress, which MarsEdit relies upon when connecting to your blog. Normally, if an incorrect or empty username and password are provided, WordPress responds with a request to prompt the user for a password. WP-SpamShield changes this behavior so that WordPress’s usual response is not delivered.
To work around this problem, you need to manually enter your username and password into MarsEdit:
- Click the blog’s icon in the main MarsEdit window.
- While holding the Option key on your keyboard, click the Blog menu at the top of the screen, and select “Enter Password”.
- Carefully retype your correct login and password.
Now when you refresh the blog again, it should connect without prompting and without presenting an error.
