It needs connectivity to wordpress.org and is timing out. I am behind a corporate firewall. I have never had this issue come up before in previous versions. Why does themes.php need access to wordpress.org and what can I do so it doesn't (or maybe something that will allow me to use my proxy settings).
Adding in error message:
PHP Warning: 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. (WordPress could not establish a secure connection to WordPress.org. Please contact your server administrator.) in C:\inetpub\wwwroot\ticket\wp-admin\includes\theme.php on line 298
This is definitely new to 3.7. We have 3.6.1 installed 4-5 times and no issues. I would have people chopping off my head if they couldn't change their theme.
Update: 3.8 fixed a lot of the major issues. However we still cannot find plugins, find themes or get and of the dashboard feeds. If anyone has a solution to these - even if it a suggestion for the proxy server, that would be helpful.
