I recently logged into my Joomla 3.3.5 site and got the following message to upgrade to 3.3.6.
When I went to do the upgrade a site from 3.3.5 to 3.3.6 and got the following error:
I was able to do a manual update. I downloaded the update package and unzip the files into my joomla install directory and the upgrade worked.
My environment is WAMP, so everything was local. This maybe different with a live site on a hosting platform.
I hope this helps someone else….
