If we install a Prestashop on an account, would the shop get upgraded whenever a new version is released ?
How would the upgrade process would be handled by Softaculous app installer ?
Softaculous does not provide upgrade option for PrestaShop versions other than 1.4
The reason is that PrestaShop have their own upgrade utility for versions 1.6 and 1.7
If you want to upgrade PrestaShop installations of versions 1.6 or 1.7 you will have to follow their guide.
