Joomla Web Hosting Canada

From the official Joomla site:

Joomla 1.0.13
"This release features several improvements to the password storage system designed to help protect the future security of your Joomla! powered website.  These changes will cause compatibility issues

with some 3rd Party Extensions, especially bridges.  If your Joomla! site utilizes bridges to other applications or extensions that have their own login system such as Community Builder, Virtuemart, or others you should not upgrade your site until those extensions have also been updated."

JoomlaWebHosting will continue to install version 1.0.12 until this issue is resolved.

UPDATE:

Most extensions now updated. We now install 1.0.13
