#39802 new defect (bug)

Multisite: "No importers are available" error message shown to site admins, but not to network admins

Reported by: thomaswm's profile thomaswm Owned by:
Milestone: Awaiting Review Priority: normal
Severity: normal Version: 4.7.2
Component: Import Keywords: has-patch
Focuses: multisite Cc:


Steps to reproduce:

  • Consider one site in a WordPress multisite install.
  • Verify that the "WordPress Importer" plugin is installed in the network, but disabled on this specific site.
  • Log in as a site administrator.
  • Click on "Tools" and "Import".
  • You'll see the message "No importers are available."

If, however, you open the same screen as a network admin, WordPress will show a link "Run importer". If you click it, WP will activate the "WordPress Importer" plugin and proceed with the import process.

This inconsistency is confusing to users. It does not really make sense because both site admins and network admins have the necessary capabilities to activate the importer plugin (provided that it is installed).

It seems that lines 33ff. in wp-admin/import.php are responsible for this behaviour:

if ( current_user_can( 'install_plugins' ) ) {
        // List of popular importer plugins from the API.
        $popular_importers = wp_get_popular_importers();
} else {
        $popular_importers = array();

Site administrators do not have the install_plugins capability, but they do have the activate_plugins capability, which is sufficient if the specific importer plugin is already installed.

This problem still exists in 4.8.1

This would be a good first bug fix

Due to this same problem, the WordPress importer is also not available to network admins if you've disallowed plugin updates in wp-config.php

define('DISALLOW_FILE_MODS', 1);

The ticket description mentions that the plugin is "disabled on this specific site." The current patch does not add a link to activate the plugin, but it can show site administrators the "Run Importer" link when the plugin is activated on that site.

[14759] added the install_plugins condition (for two items, and the other involves installation).
