PHP Versions

new

What version of PHP does this work on? I'm thinking about upping my PHP version, and want to make sure this is PHP 8.x ready.

Chex is compatible with PHP 8.2

Is chex compatible with php 7.1? It will install and function in sandbox mode on my prestashop 1.6.17 site, but will not complete payment with stripe. It shows a loading page for a moment, then just goes back to the previous checkout view. Also, I have PS checkout module, but chex does not seem to show paypal as an option. So it is completely non functional for me currently. I love the interface, and would like to make this work for my site. All other options are so dated looking and clunky.

I believe it should run on PHP 7.1. But I confess I didn't test it on such old php version.

Look into your php server error logs if there are any errors (warnings should be fine)

This is the only thing in the log: [02-Feb-2024 11:57:49 US/Pacific] PHP Warning: DOMDocument::loadHTML(): htmlParseEntityRef: no name in Entity, line: 1 in /home/xxxxx/public_html/xxxxxxxxx.com/modules/gmbreadcrumb/gmbreadcrumb.php on line 54.

I disabled the breadcrumb module, but after you click pay, it says "redirecting to payment page", then takes you back to the previous view. 1.6 uses php7.1 so I cant try it with a higher version. I dont really understand what I am seeing. I just want a nicer checkout, and would like buttons for "pay with card", apple/google pay, and paypal.
