Steps to reproduce:
- Create a page such as:
<maplink latitude="43.739" longitude="43.528" zoom="7" show="a,b,c,d"/>
- Refresh the page, click on the link.
- The map may not appear at all
- Seeing in the console::
VM2434:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0
Although this sounds like a corner case at first, I noticed it on Russian Wikivoyage... The maplink in the corner is broken. This makes it a very high priority bug :/
