Reply To: is there any option to say the customer which option they miss to select

Hello,

To change the text of the message of the “select options” pop up that is displayed on the product page.

You need to use loco Translate plugin. Please Go to Dashboard >> Loco Translate >> Choose the path from where you want to translate the string.
