Hello

I had my json markers layer and my map working for several weeks, and today I entered map administration to change map center coordinates. When I click on save I get an error (drupal log) that says "Illegal option EPSG:3857 in element Map projection" (translated from Spanish).

I don't have a projection selected (I didn't have any projection selected either when it used to work) and my JSON markers have a different projection code selected. So, if I give up and select the only radiobutton projection available (the one my markers have) I can save the new map center but the map stops showing at all (not in preview pane not in the pages where it used to work fine). Even in Content types -> Display management the map is not available for selection in the dropdown list.

I don't understand what has happened. Some module update screwed my maps?

I hope you could give me a hint to solve it.

Thanks in advance.
