    Yes, I installed it on the newest version of zen cart(v1.5.7d), and it's not working but just keep refreshing the product info page about 2 times/every second.
    And when I tested it on v1.5.6c, there is no problem.

    Found by going back 2 or 3ish pages.

    Explanation of why that is occurring is provided back there.

    I've been testing locally so far and everything works fine.
    My version is v1.5.7d, the local PHP version is 7.4, and so is the server.
    But whenever I move the site to the server, the plugin doesn't work at all except for loading images all the time when I input the quantity.
    Any ideas?

    Several come to mind, though not all specifically related to the plugin and in no particular order: files exist in the server that are not in the local version, file differences between the two, database differences that have some affect, two or more observers trying to monitor the same notifier but are loaded in a different sequence on the site than the local version, that there has been done html validation differences between the output, differences in jquery versions, etc.

    Basically that there is a difference between the two that has brought out a difference in operation. Look for logs, create logs if necessary, include browser (javascript/jquery) as well, etc.

    Another mod that has fallen foul of changes made to the ZC 1.5.8 `shoppingCart` class which reassigned some variables
    from generically `public` to specifically `protected`.

    The mod is going to require some reworking. Not sure who's managing this one now.

    Thanks for that, I knew it existed but couldn't for the life of me remember where I had seen it - or whether I was just dreaming about it. I'll take a look and see if it helps.

    I haven't tried installing this v4.0.0 but it looks as though it makes use of the same variable as v3.2.1

    Code:
    shoppingCart->total_before_discounts
    A workaround on the site I'm currently working on is to remove the offending lines from dynamic_price_updater.php. I don't use the native ZC specials, sales and discounts (just @swguy's Quantity Discounts) so it should be ok.
