How to remove text in the footer?

Could you please specify the theme you have purchased or send your site URL so that we can suggest you a solution?

Hi,
The complete copyright text will be removed i.e. Design and Developed by Themespride. Add the below code at Appearance -> Customize -> Additional CSS

span.credit_link {
display: none;
}

If you want to add your own then you need to add it at Appearance -> Customize -> Theme Settings -> Copyright Text.

Thanks
