This is the correct one, at this time:

if ( ! function_exists( 'presscore_mod_portfolio' ) ) {

    function presscore_mod_portfolio() {
        return;
    }
    presscore_mod_portfolio();

}

if ( ! function_exists( 'presscore_mod_testimonials' ) ) {

    function presscore_mod_testimonials() {
        return;
    }
    presscore_mod_testimonials();

}

if ( ! function_exists( 'presscore_mod_team' ) ) {

    function presscore_mod_team() {
        return;
    }
    presscore_mod_team();

}

if ( ! function_exists( 'presscore_mod_logos' ) ) {

    function presscore_mod_logos() {
        return;
    }
    presscore_mod_logos();

}

if ( ! function_exists( 'presscore_mod_benefits' ) ) {

    function presscore_mod_benefits() {
        return;
    }
    presscore_mod_benefits();

}

if ( ! function_exists( 'presscore_mod_albums' ) ) {

    function presscore_mod_albums() {
        return;
    }
    presscore_mod_albums();

}

if ( ! function_exists( 'presscore_mod_slideshow' ) ) {

    function presscore_mod_slideshow() {
        return;
    }
    presscore_mod_slideshow();

}
