How to remove pinterest button was embed on my site

If you mean the little red Pintrest button its most likely bc you have a pintrest account and the pintrest plugin in your browser. Then it will show up, not only on wordpress.

If you dont mean that maby its a theme setting under social icons and that there is a link to pintrest there.

But i would guess on the first one

Sorry, but you’re using a premium/paid theme. It’s best to go to the support site where you bought the theme – https://themeforest.net/ – for help with customizations and issues. You paid for support when you bought the theme, so you should contact the people who sold you the theme.
