Helo! You were correct. The problem was the plugin. Thank you for your help!
I would like further help. How can I make the sale tag positioned on the right and not the left as the default? I tried to change the css but it didn’t look good because the products are presented in different sizes and the tag in some is disfigured (Home, categories and individual product).
I would also like to know if it is possible to put the % before the Sale, because I would like to put it ex: 50% OFF
