I did not find a support category for the Joomla CMS Update component. That's why I post the question here.
I spent a lot of time figuring out why the CMS Update component was giving me a "Unexpected HTTP status 302" message when downloading the new Joomla release package.
It seemed the url to the release package returns a redirect to a Amazon location. Since the website is on a shared hosting server the open_basedir php setting was set by default. This setting prevents cURL to follow redirects.
Fortunately, I could set the open_basedir setting to 'none' where after the update component was able to download the release package and update Joomla successfully.
Could you build in a detection for this situation?
Thanks for the great components.
