threadi, thanks for the tip. I have determined the plugin: “Rhythm Addons” as a optional part of the rhythm theme. When i deactivate this plugin, the two lines are no longer included in the html code. I opened all files of the plugin and searched for “fonts.googleapis.com”. In only one file I found what I was looking for – where it says “http” instead of “https”. However, modifying the url to test it did not bring any change. Maybe someone has a tip?
$id = ( $id ) ? ' id="'. esc_attr($id) .'"' : '';
$class = ( $class ) ? ' '. sanitize_html_classes($class) : '';
$customize = ($font || $font_color || $letter_spacing || $transform || $font_style || $font_weight || $font_size || $margin_top || $margin_bottom ) ? true:false;
$output = '';
if(strpos($font, 'google') !== false) {
$font_weight_type = ($font_style == 'italic' && $font_weight ) ? $font_weight.$font_style:$font_weight;
$ifont_name = str_replace('google_web_font_', '', $font);
$font_name = str_replace(' ', '+', $ifont_name);
$output .= "<link href='https://fonts.googleapis.com/css?family=".esc_attr($font_name).":".esc_attr($font_weight_type).", 400, 300, 600' rel='stylesheet' type='text/css'>";
} else {
$ifont_name = $font;
