 Hello,

Despite searching and reading, I haven't found out why I'm having this behavior, which looks more like a setting than a bug, but is still surprising: I'd like to apply a discount of €15 (incl. VAT) to baskets of at least €300 (incl. VAT).

When the rule is created and saved, both the discount amount and the amount are then marked in HT (Apply a discount / Amount / 15: the drop-down menu is set to HT (ex taxes) whereas I chose TTC (tax included)).
Can be bypassed by specifying 250 excl. tax instead of 300 incl. tax, but one consequence: if the amount is not reached, the warning announces “Amount 250 € minimum”, which is not clear. Am I missing a setting?

Thanks for your help.

NB: I tried RTFM first, the official guide has a link to shopping cart rules but 404 https://help-center.prestashop.com/hc/fr/articles/115000595512

Hi, first at all, can you downgrade your PHP version to see if it's the cause

Infos error on opening this thread, the site has in fact always been under PHP 8.1.

However on switching to PHP 7.3 I realize the bug does *not* happen under that obsolete PHP version, to which I cannot revert for obvious security reasons - and the official recommended PHP for PSP is indeed v 8.1.

Thanks for the tip, all I can do now is test the very latest Prestashop version to see if it was fixed later.
