This seems odd to me because if you're signing on a user you shouldn't already be signed in... therefore your permissions shouldn't matter.

It may be a bit of an odd way of going about it, so that could be causing the issue. Here's the code:

function login( $user_name, $password ) {
    $creds = array();
    $creds['user_login'] = $user_name;
    $creds['user_password'] = $password;
    $creds['remember'] = false;

    $user = wp_signon( $creds, true );

    if( is_wp_error( $user ) ) {
        $result = $user;
    else {
        /* do some other stuff */

    return $result;

This is found on a separate page used for web services... this page loads the proper WordPress functions with:


And is posted to via jQuery from the front end.

Worth noting that other WP functions such as interaction with global $wpdb works in this file.

What is the exact error WordPress is giving you when you use this? – EAMann Jul 9 '12 at 20:25
fail insufficient_permissions: Current user does not have the permissions to execute that function – Matt Jul 9 '12 at 20:39
Maybe I'm not understanding the Question, but the sample code works for me, if run as an autonomous PHP file. Are you getting this error in jQuery? Because I only found 3 occurrences for "insufficient" in WordPress core... Snapshot: cl.ly/I4FS – brasofilo Jul 14 '12 at 15:49
As @brasofilo said, there is no such error in the WordPress core. Exactly what happens when you run this code and exactly what is the real error you are getting? – Michael Hampton Jul 15 '12 at 21:03

A quick Google on that error garners two results: this question, and an indexed error response from a script named venue_admin_api.php.

Is that your website? Or are you using the same library?

Regardless, somewhere in your codebase (ignoring WP core), that error exists - find it, & post the surrounding code, otherwise I can't see how we can help any further!
