Janett Posted May 10, 2019 Share Posted May 10, 2019 What is your Prestashop version ? https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/ Link to comment Share on other sites More sharing options...
Himanshubishtt Posted May 10, 2019 Author Share Posted May 10, 2019 Sir, my ps version is 1.7.2. Thanks Link to comment Share on other sites More sharing options...
Janett Posted May 10, 2019 Share Posted May 10, 2019 Prestashop 1.7.2 is not compliant with PHP 7.2, only PHP 7.1 maximum. Prestashop 1.7.5 is compliant with PHP 7.2 maximum Moreover if Prestashop is compliant, your modules can be too oldest to be compliant with PHP 7 1 Link to comment Share on other sites More sharing options...
AndersDreyer Posted May 10, 2019 Share Posted May 10, 2019 (edited) Can you update(downgrade) modules directly though the ftp or what should he do? Facing the same problem... Edited May 10, 2019 by AndersDreyer (see edit history) Link to comment Share on other sites More sharing options...
Himanshubishtt Posted May 10, 2019 Author Share Posted May 10, 2019 Thank you so much for this valuable information. So I changed my PHP version to normal which is 5.6.40. Now everything works fine. But just for future reference if I want to change the PHP version to 7.1 on Ps 1.7.2, I can do it without any problem, right? Regards, Link to comment Share on other sites More sharing options...
Janett Posted May 10, 2019 Share Posted May 10, 2019 @Himanshubishtt Prestashop 1.7.2 is compliant with PHP 7.1 maximum. If you want to use PHP 7.2 you need to upgrade Prestashop to version 1.7.5 If you want to use PHP 7.3 you need to wait the release of Prestashop 1.7.7 and follow the work in progress here : https://github.com/PrestaShop/PrestaShop/issues/12461 Link to comment Share on other sites More sharing options...

kaynaprod Posted January 14, 2021 Share Posted January 14, 2021 Hello my web host has forced php 7.3 and I can't change it. unfortunately I did not upgrade my prestashop and suddenly the backoffice no longer works. Is there a way to upgrade prestashop without having access to the backoffice / admin? If not, do you have a solution for me? thank you in advance Link to comment Share on other sites More sharing options...
Prestachamps Posted January 14, 2021 Share Posted January 14, 2021 There is not much you can do, beside ::) 1.. Ask you hosting to create a full backup of your store (gzIp all the files) and the DB 2. Ask them if they provide you a location here you can make upgrade (lower PHP ) and once it's done copy it back. Other option : - change your host - one which do not care about their customers need - not worth to be kept. Cheers, Leo Link to comment Share on other sites More sharing options...
