When I first installed your plugin, I had to opt out of displaying
"Powered by web designer". However, when I tried to opt out it didnt remove the link. I had to go into the code to remove this.
This is against WP plugin repository guidelines:
"10. The plugin must not embed external links on the public site (like a "powered by" link) without explicitly asking the user's permission. Any such options in the plugin must default to NOT show the link."
