Hangs on "checking credentials…"

Please provide the plugin version, browser & version along with OS. This sounds similar to a previous bug that was fixed in the latest release.

This issue is ubiquitous. I’m always up to date, running the latest versions of everything.

Thanks Hassan,

Have you tried disabling all active plugins and tested the login feature? It’s possible a plugin in conflicting as some have found in the past with an issue similar to this.

Hey, Cole.

It appeared to be the theme that is causing the issue, not a plugin. However, I am unable to identify the source of the conflict. I tried dequeuing all of my theme’s scripts to see which one was the culprit but nothing has changed. I kept stripping the theme from other elements but again I did not get any results.

I am of course assuming that it is probably a JS issue, but it might also be related to PHP (not sure). My theme does nothing related to login/registration at all, so I’m a bit lost now.

Do you have any idea where (or what) I should be investigating? What WP areas does your plugin alter?

I also have a live link where you can see this. If you have some time to take a look, I can send you a link. Otherwise, I’ll just keep tackling this until I figure out something.

Hi Hassan,

The notifications in the modal is all done via AJAX, so it would be a JS issue some where. You can send me a link and I can take a look via the front-end. If you don’t wish to share the link on the forum you can email at cole (at) colegeissinger.com

Just to clarify, you changed your theme to another and got the plugin working and that’s how you were able to narrow it down to your theme?

Thank you Cole.

Yes, exactly. I switched to twentytwelve and the plugin worked.

Will email you a link.

Greetings Cole,

Have you had any luck with this?

Hi Hassan, I’ve been tied up with work and a pending wedding in 3 months so I haven’t had any time until just now.

Looking through it looks like when the plugin queries your WordPress Ajax file it’s returning a 302 error, which is similar to this ticket .

This issue has since been fixed but it appears something in your theme is causing the Ajax to break in the plugin. With out being able to directly access your theme I can’t debug from my end. I see there are a number of Ajax scripts loaded in your theme, I would say, try disabling each of those one at a time and see if anything changes with the login.

I found the culprit!

I had this code snippet in my theme’s functions.php file:

function my_restrict_admin() {
    if ( ! current_user_can( 'manage_options' )  && $_SERVER['PHP_SELF'] != '/wp-admin/admin-ajax.php' ) {
        wp_redirect( home_url() );
    }
}
add_action( 'admin_init', 'my_restrict_admin', 1 );

Which restricts non-admin users from accessing the backend and redirects them to the home page. Removing this makes the login works.

However, if you notice, I am already saying && $_SERVER['PHP_SELF'] != '/wp-admin/admin-ajax.php' which checks if the call is not for the ajax file, but the plugin still won’t abide by this. Interestingly, all other ajax calls by other plugins work fine with this code present. Maybe you want to double-check something?

So, looks like that was not the best way to do what I wanted. I modified that redirect code to this:

add_action( 'init', 'my_restrict_admin' );
function my_restrict_admin() {
    if ( is_admin() && !current_user_can( 'manage_options' ) && ( !defined( 'DOING_AJAX' ) || !DOING_AJAX ) ) {
        wp_redirect( home_url() );
        exit;
    }
}

…and everything works good now. Thanks, Cole.
