Until we have fixed this problem, you can use the following JavaScript command in the console:
jQuery(‘input[name=”wpseo_amp[amp_site_icon]”]’).val(”);
jQuery(‘input[name=”wpseo_amp[amp_site_icon_id]”]’).val(”);
You can open the console by right-clicking on an element in the page and select ‘inspect’ and click on the console-tab or use:
Chrome + MacOS: command+option+J
Chrome + Windows: control+shift+J
Firefox + MacOS: command+option+K
Firefox + Windows: control+shift+K
Paste the lines and press enter to execute them, the field should be cleared.
Press “Save” to save the changes.
