  • Comment out those two lines ad see if you can get in. just put a double slash (//) at the start of the lines.

    Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

    Also like @juggledad said, what is one those lines in your wp-config.php file. Maybe try removing them or commenting them out to see if that resolves the issue.
