If you are using or administrating WordPress Multi-User you may have come across the following error message for new users creating just a login name (not getting blog):<\/p>\n
\nYou do not have sufficient permissions to access this page.<\/p>\n<\/blockquote>\n
This problem can get pretty frustrating if you are using a single blog on WPMU that has several users. For example, I created one blog for my class this Summer that has six additional users. Each of the students created a login name without a problem, but when they tried to sign on to the site (and I had given them all editing permissions) they received the above message. This can be worked around clunkily with a couple of hard refreshes and a handy edit button on a post, but there is a better hack.<\/p>\n
On the WPMU forums I found the following solution<\/a>. According to this thread, and others like it, this is a more general issue with WPMU 1.0 and hasn’t really been addressed as of yet. However, as is often the case with open source applications, someone has come up with a quick hack that has worked perfectly for me thus far. Below is the code for the plugin to make this problem go away.
\n<?php
\n\/*
\nPlugin Name: ADRX No Caps User Login
\nPlugin URI:
\nDescription: This plugin determines what happens when a user logins in at a blog for which s\/he has no capabilites.
\n*\/
\nfunction adrx_nocaps_login() {
\nglobal $current_site, $current_blog, $current_user, $user_ID, $wpdb;
\nif (!is_blog_user() || !is_site_admin) { \/\/ no caps and not site admin
\nif ($current_blog->domain==$current_site->domain) { \/\/ logged in at main site — no caps
\n\/\/ if user has blog, send user there - code copied from menu.php
\n$primary_blog = $wpdb->get_var( “SELECT meta_value FROM {$wpdb->usermeta} WHERE user_id = ‘$user_ID’ AND meta_key = ‘primary_blog’” );
\nif( $primary_blog ) {
\n$newblog = $wpdb->get_row( “SELECT * FROM {$wpdb->blogs} WHERE blog_id = ‘{$primary_blog}’” );
\nif( $newblog != null ) {
\nheader( “Location: http:\/\/” . $newblog->domain . $newblog->path . “wp-admin\/” );
\nexit;
\n}
\n}
\n}
\n\/\/ user has no caps here
\n\/\/ user either has no existing primary blog of his\/her own or did not log in at main site
\n\/\/ redirect to front page of the blog at which s\/he logged in
\nheader( “Location: http:\/\/” . $current_blog->domain. “\/” );
\nexit;
\n}
\n}
\nadd_action(’admin_menu’, ‘adrx_nocaps_login’);
\n?><\/code><\/p>\nJust copy the above code into a text editor, save it as adrx.php, and copy it into the mu-plugins folder of your WPMU install. That’s it! Hopefully this will be solved in the next version, for it is a pretty big problem if you are going to have a multi-user blog within this environment.<\/p>\n
