Please stop marking posts as resolved when they aren't. Is there a way of writing on the sign up form “please enter what you would like your store url to be” as ive had 2 customers now enter the full address for their facebook page or their website as they think thats what they have to enter.
The input is taken through “\wp-content\plugins\dokan-plugin\classes\template-settings.php” open this file and go to line number 240 and you will get to see all the codes for taking links. You can write what ever you want to show.
If you feel confused or need more info, please let me know.
