All of our wordpress sites were functioning fine until we upgraded to version 3.4.1. After the upgrade, we started getting the following error on install-plugin.php and theme.php pages:
An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.
There have been numerous unresolved threads on this forum and I am surprised that no one from WordPress has stepped in and offered a patch. Please be kind and help. If there is something wrong with our hosting then atleast give us instructions on what tell our host (someone brought this up on forums that there has been some API changes since WordPress 3.4).
