Upgrading - Auto upgrader not detecting version in Upgrading PrestaShop from a previous version Posted November 16, 2012 Hiya, Testing the auto upgrade tool... I am on 22.214.171.124 and when I install the module I get the below - which is wrong as there are many updated upstream from my version. Any ideas appreciated: Congratulations you are already using the latest version available ! Your current prestashop version 126.96.36.199 Latest official version for channel minor N/A In Version comparison I also get: PrestaShop Original version: [TECHNICAL ERROR] Unable to check files for the installed PrestaShop version differences between versions: [TECHNICAL ERROR] Unable to generate diff file list between 188.8.131.52 and . I had the same issue, but Fixed it. Probally u dont have allow_url_fopen off in ur php.ini. U can check this simply by going to ur admin start page, if there's a message that allow_url_fopen is not on, this update module doenst work. My advice, turn it back off after u update, for more security.
