thanks for responding so quick.
so, i change to Twenty Nineteen oficial wordpress theme, those js error are no more but the icons are still missing, also turned off the Marker Clustering option.
The code i wrote is correct, right?
this case 'arreglo-calles'
is the category slug, and this $iconURL = get_bloginfo( 'stylesheet_directory' ) . 'https://salvemosvidas.com/wp-content/uploads/2020/01/arr.png';
the full icon adress
and the location is in function.php, right?
i don`t know what else to do
thanks in advance
