Woohoo!
Thanks to your pointer, I found out that the theme I use as a boilerplate was probably causing the mess with the big scary error I got.
I have also done some more testing and I just discovered that the original problem I posted (which was: all of a sudden I can’t use autocomplete anymore on the post form), was caused by loading the javascript to the google maps api like this, in the footer:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false">
I was loading the api in my theme’s footer.php file, and I have moved it to the actual page where I was using it. Problem solved!
If you have a moment I wouldn’t mind a brief explanation why this is, as I’d love to be educated a bit more.
Thanks for all the help!
