The shop is set up wilth multi store:
I've already checked the groups settings and they are the same for both stores.

Hi @nielsverhoeven84,
I did not manage to reproduce the issue with PS1.7.5.2 & PS1.7.6.0rc1.
I attached a screen record.

Thanks to check & feedback.
Hello @khouloudbelguith,
For every customer group (for my store group and each individual store) it shows inclusief belasting, the value of that option is 0.
@nielsverhoeven84, for the customer group, the Price display method is "Tax included" as described in this screenshot

What is the exact option which has 0 as a value?
Thanks!
@khouloudbelguith
The HTML is:
<select name="price_display_method" class=" fixed-width-xl" id="price_display_method">
<option value="1">Exclusief belasting</option>
<option value="0" selected="selected">Inclusief belasting</option>
</select>
0 is including taxes, but that is only working on the first store
@nielsverhoeven84, yes, about the HTML, it is normal =>
Tax excludedTax included
About your issue, We need to retrieve the PHP error log and the debug mode report in order to find out what's wrong.
Thanks!
I've solved this issue.
It seemed that customer groups weren't enabled for the second store.
@nielsverhoeven84, thanks for your feedback.
Feel free to open a new one when needed.
Thanks!
I was wrong, after checking more thorough, I saw VAT was still calculated wrong.


@nielsverhoeven84, have you the same issue reported in this ticket: https://github.com/PrestaShop/PrestaShop/issues/14446?
Thanks!
Yes, but it shows differently for logged in / not logged in users.
@nielsverhoeven84, yes, the first issue, in the Fo => Ok
The second issue => in the Bo > product page => similar to #14446, is it?
Thanks!
Yes, it shows all prices without VAT in BO, although VAT of 21% is selected.
@nielsverhoeven84, we are aware of this issue, it is added to our debug roadmap.
Your ticket is a duplicate of #14446
So, I close it.
Thanks !
