1-Click upgrade not working in Upgrading PrestaShop from a previous version Posted September 27, 2020 31 minutes ago, Crezzur said: @Presta_Lost more information about manually upgrading can be found here https://www.sunnytoo.com/6996/manually-upgrade-prestashop @YoyoLuke its a default module of Prestashop https://addons.prestashop.com/nl/migratie-backup/5496-1-click-upgrade.html Unfortunately maybe my version is too old. If you click on that link you provided, there's no option to download it - and from my backend when I do a search for it - nothing comes up. I do have a notification on my backend that says "You can update to PrestaShop 18.104.22.168 - download now" and the button takes me to the link you posted. I can only assume that for newer versions it's a default, but for older versions it required to be manually downloaded, and for some reason Prestashop have taken it away. I have tried to email support but to no avail. I had been meaning to transfer to shopify for a while, but this has unfortunately forced my hand.
