Some people were having issues detecting whether their .JS code was properly installed, especially if the code was inserted using something like Google Tag Manager.
A new javascript detection routine has now been put live which should fix this.
In addition, a few days back, we modified the javascript code itself, so that (if you want) you can put the actual code in the .js file onto your site, instead of the .js file itself. This would mean that you are only calling data files from our servers, which should satisfy security fanatical admins. Doing this would also allow you to decide whether you just want the schema, or the links or (by default) both.
