Dear Daniella,
Great! So replace your code with:
add_shortcode( 'wpv-post-getpaged', 'wpv_getpaged');
function wpv_getpaged(){
if(($_GET['wpv_paged'] == '') || ($_GET['wpv_paged'] == '1')){
return('0');
}else{
return('1');
}
}
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
