I just update a store from prestashop 1.6.1.17 to thirty bees 1.0.8. The update was quite simple, but when I try to configure coreupdate after installing it, I receive this error:
[PrestaShop] Fatal error in module file :/var/www/prestashop/public/modules/coreupdater/classes/Retrocompatibility.php:
syntax error, unexpected '?'
I think this is related to the php version, which is why I update to thirtybees. At the moment I have php 5.6, I try php 7.2, 7.4 and 8.1, but none of this works, it give me 500 error in administration. How can I change my php version and do coreupdate work?
Thank You for your help
