Did the installation, to plugin setting, choose a map and used the code in a text widget and placed it in the sidebar. Tried a few options but the map did not show.

Update: it does work fine in a normal page or post, I cannot get it working as a text widget in the sidebar.

Unfortunately, my site only shows the menu, an no text anymore when installing the plugin.
