Hi @Ortrun ,
Welcome to the Buttonizer Community 🙂
I've just checked your website and it seems that the CSS rule .ulpb_PageBody a:active, .ulpb_PageBody a:hover
of your theme is affecting the text color of all Buttonizer buttons.
You could fix this by adding :not(.buttonizer-button)
to the CSS rule.
This will look like this:
.ulpb_PageBody a:not(.buttonizer-button):active, .ulpb_PageBody a:not(.buttonizer-button):hover {
Let me know if this helps 😎
