[SOLVED] Unable To Open My Admin Platform after Upgrading to PrestaShop 1.7.8.7

[Wellness99]

Dear Prestashop Community,

Urgently need your help. I just upgrade my shop to Prestashop 1.7.8.7 via 1-Click Upgrade module. After completing the upgrade, I reload my shop and it shows HTTP ERROR 500.

Then, I follow a tutorial that guide me how to enable debug from my File Manager. After awhile it enable my Prestashop login page and when I clicked login button, it gave me this sentence "Composer detected issues in your platform: Your Composer dependencies require a PHP version ">=7.2.5".

What should I do? I don't have IT background and this is my first time using Prestashop.

I'm totally need your help.

It is clear.. ask your provider  to switch PHP to at least 7.2
After that, be prepared to have issues with the some third party modules if they are not PHP7.2 compatible case in which contact the developers and ask for newer versions.

Thank you so much, Rhobur. I've changed my current PHP to the larger one. Everything seems good as for now. 😊
