I have the same problem occurring on a new (created 2 days ago) small multi-site: https://malartu.org
It happens when I attempt to search to install new plugins from the network dashboard as super-admin.
Everything is new: 3.4.2, only Akismet and WordPress Importer as existing plugins.
any idea?
I also get the same error when searching for new themes.
If the problem is happening when you search plugins or themes its probably because your connected to a proxy and you need to configure it on your wp-config.php
/** EXAMPLE – proxy settings */
define(‘WP_PROXY_HOST’, ‘proxy.url.com’);
define(‘WP_PROXY_PORT’, ‘1234’);
define(‘WP_PROXY_USERNAME’, ”);
define(‘WP_PROXY_PASSWORD’, ”);
define(‘WP_PROXY_BYPASS_HOSTS’, ‘localhost’);
I’m having that exact same problem, and added that code into the wp-config.php file and still nothing!
– I reinstalled wordpress and MU version of the site as well
– my server is behind a load balancer and firewall (school server)
This is the first time wordpress and a server has ever gave me problem
Any ideas?
SOLVED
in my case, it was simply the SITE URL left blank in Settings -> General
Filled with mu site URL, everything started working again.
i found out enabling WP_DEBUG in wp-config.php, and i got this error:
“Notice: Undefined index: host”
Thank You so much mario.andrade
It was a proxy problem and solved now 🙂
