Meta Box

Hello Sam,

It is the default WordPress error message, located in the file wp-includes/user.php line 262 and there isn't a filter hook or option to change this message.

Hello,

I am not able to understand were to enter as normal custom fields in the meta box settings

It is the custom fields that you added to the field group product-price, product-information.

however in the regular view the "+ Add Media" renders like "Choose File"

Each field type will have a different add button text. You are using the field type image so it will display "Choose file" button. You can use the field type single_image and recheck this.

all the: "Add New producer", "Add new country" etc they are not available

You are using the field type taxonomy, please make sure the option "Add new" is enabled when you create the custom field, screenshot https://imgur.com/2zwmuGY

I've escalated this issue to the development team to fix it. The fix will be included in the next update of Meta Box.

Thank you.

Hello Ivan,

The code is hooked to the Elementor action so it won't work in the admin area, column startdate. You can remove the meta query $query->set('meta_query', $meta_query); of the example code and keep your own code to sort by startdate field.
The date format should have the same field format that is saved to the database.

Please follow the documentation https://docs.metabox.io/fields/date/#date-format

Hello Keith,

are you just saying the very first row in the field set MUST be a tab?

Yes. If you want to use the tab field, you have to add it as the first field of the field group. Check this screenshot https://imgur.com/UarfXSu

Please share your site admin account by submitting this contact form https://metabox.io/contact/
I will take a look.

Hello Raj,

It isn't possible. The tab must be added to the field group first, then other fields. It only works as a top field instead of a subfield in a group field.
