1.) Tried it:

.my_icon
{
color: #a28a0a !important;
}

don´t works.

Tried it the direct way:
get_the_term_list( $post->ID, 'person-category',""," <span style='color:#a28a0a'> ★ </span> ","" );

don´t works.

2.) Solved, like said, stupid question 🙂

3.) Is there any workaround, to regulate the time, between going on the pic with mobile and change to profile ?

4.) Solved, works perfect.

5.) The google analytics code, which i put into the options, is implemented at thr wrong place. It is not in the header of the page.
