i also followed your advice, and installed the open street map, but the map shows up ONLY after interacting with it: before, there is only the grey background and the marker, but no map until you move or zoom it.

hi Yigit, i inserted and saved there several times, simply the theme first saves the option, and after a while, when you go back to the same page, the key is not there anymore… i tried this about 20 times.
