I appreciate your comments. Nevertheless, I can’t find the locations you mentioned. the theme is twenty thirteen, WP is 3.7.11. In appearance’ theme settings tab is missing. appearance-editor is also missing. Is there any way to fix this. If the last choice is CPanel, can anyone help me how to do it there, because CPanel is truly unknown to me, ho wit works?
Besides in appearance-widget for the right slider there is not any URL mentions which I can change, it is just written a text which isn’t connected to video-youtube link anyhow.
