I'm working on upgrading one of Magento site version 220.127.116.11 to 18.104.22.168 via Magento Connect. For some reason after I click on "check for upgrade" button, the page does not show any drop options except "reinstall" and "uninstall" on the available column, all fields are empty where they were supposed to version 22.214.171.124 or the latest version of modules.
This issue doesn't occur on another Magento site that I upgrade from 126.96.36.199 to 188.8.131.52.
Could this be permission issue or glitch on Magento connect? or does upgrading from 184.108.40.206 to 220.127.116.11 has be done manually outside Magento Connect at this point?
