If you would rather not use the built-in hover button functionality that comes with Tasty Pins, you can disable it easily from the Tasty Pins Settings.
Log in to your WordPress dashboard, then select Settings -> Tasty Pins.
Select "Off" from the Tasty Pins hover button dropdown and save your changes.
Keep in mind...
The Tasty Pins hover button uses the default Pinterest hover button functionality. Benefits of using the default Pinterest save button are as follows:
Duplicate buttons don't show when the user has the Pinterest browser extension installed
You can be sure that the button uses the most up-to-date code and recommendations from Pinterest
Pinterest optimizes their save buttons for user interaction - potential for more pins
No conflicts with the alt text and the Pinterest text
If you are using another hover button and you feel that the above are important, you may want to check with your current hover button developer to make sure they use the default Pinterest hover button.
