Gmap map would not display so I updated...

The gmap installed on our website has worked excellently for years but just recently the map showed what appears to be a Google set up issue.

I reinstalled the gmap extension with com_GMapFP_j3_60F.zip. It is a J3 site still.

Now the menu items set up in the website all go to error 404.

I have tried recreating the menu items but the result remains the same.
