I had to re-generate my Googlemap API, I had not done it since 3 years maybe.
After that I put the new API code into my WP theme and my SiteOrigin parameters, I have lost a function of the Googlemap widgets generated by SiteOrigin.
It looks like I can only put an icon and info on the central marker of the map, but every other markers have disappeared, even if I try to create a new widget. In the editing menu, nothing has changed, I can still enter info for additional markers, but then only the central one is displayed.
