  • I just got a similar set of warnings, but duo stopped working altogether. Both warnings refer to the same line as mentioned above by Chris: duo_wordpress.php on line 403

    Warning: file_get_contents() [function.file-get-contents]: https:// wrapper is disabled in the server configuration…


    Warning: file_get_contents( [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in…

    I tried uploading an older backup of the plugin, and the warnings disappeared but now it says:

    ‘Pushed a login request to your phone…
    No response. Please try again.’

    I ended up having to delete the plugin completely…

    We’re marking this as resolved, as we have not heard of anyone with this issue for quite some time.
