I got a similar condition but failed to fix.
After updating the translations to version 1.3 and doing upgrade from 1.2.1 to 1.3rc1 by entering 'public/upgrade' and getting a successful message, I got a homepage of only page header and footer.
The log.php logs as follows:
-------------------------------------------------------------------------------
#1 ERROR: Error: simplexml_load_file(
http://www.opengoo.org/versions.xml) [<a href='function.simplexml-load-file'>function.simplexml-load-file</a>]: failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error

What can be the reason for this?
Thank you!
