Hello @keosite

I didn't manage to reproduce your issue with PS1.7.6.8, see the attached screen record below:

Please check and feedback.

Thanks!

Hello,

Please think about following the template (I specifically asked you to not do that here).
We need at least more information about your exact steps and some screenshots.

Hello,

Thank you for your responses.
I'm sorry I don't understand what I'm doing wrong with the template.

Here a screenshot when the error appears

When I change the date of the period the date format changes from
2020-11-25 11:00:00
to
2020/11/25 11:50

Can you please provide a screenshot of the calendar you're using ? As I see here the format is indeed invalid, probably because you didn't use the PrestaShop calendar but a browser calendar, which will then override the format by using your local format.

Here is the calendar I use

Even if I change the date by writing the number, without using the calendar, the format changes.

What browser and version do you use ? Do you have any extensions ? What is your OS and what language do you use ?

[keosite]

I use :

• Google Chrome v.87.0.4280.67
• I don't have any extension
• OS : maOS Catalina 10.15.7
• Language : french

But it don't work with Firefox, Opera browsers too and with windows 10.

When I add a specific price in a product, it works but the calendar don't look the same as the calendar in discounts page :

It seems something is interfering with the date field and blocking the PrestaShop calendar. What is your Front-Office theme ? Do you use a module that use custom datepicker elements and thus could interfere with the official one ?
This is kind of a weird thing, honestly since we're absolutely not able to reproduce it (even when changing browsers and stuff) I'm afraid the issue might lie in your own configuration.

As you may know we cannot offer support here, this is not the place.

I would suggest to ask for help in the community forums or in the public Slack channel.

All right, thank you for your responses, I'll look into it.

I use avenira theme, I will look for extensions
