Hi there,
Thank you for reaching out about your question.
Unfortunately, this is a core functionality of the slider and you may need to use a translation plugin such as Polylang or install our Poedit tool that can be found here -> https://docs.themeisle.com/article/893-translating-themes-using-poedit (though I doubt it would recognize the buttons as strings and allow you to translate them.
Another way to solve it is by using custom CSS. Altough it is beyond the support services we provide, I’ll make an exception and try to help you out with this one. Please go to Dashboard -> Appearance -> Customize -> Additional CSS and add the following code (assuming you want them translated in Portuguese):
This is for Previous button:
.nivo-directionNav .nivo-prevNav{
visibility: hidden;
}
.nivo-directionNav .nivo-prevNav:after {
content: "\00AB Anterior";
visibility : visible;
float: left;
background-color: rgb(32,32,32,0.7)
}
This is for Next button:
.nivo-directionNav .nivo-nextNav{
visibility: hidden;
}
.nivo-directionNav .nivo-nextNav:after {
content: " Próximo \00BB";
visibility : visible;
float: right;
background-color: rgb(32,32,32,0.7)
}
Please let me know if it works for you. Hope this helps!
