Some users take advantage of being able to set parameters for MPEmbed by using hidden mattertags.
If you’re not use the Premium version, it’s a great way to avoid a long URL full of parameters – and a great way to be able to change options after your client has already published their space.
One of our users emailed me because MPEmbed was not loading. I realized that one of his Mattertags had the title ‘info’ – for some useful information that he was displaying in his tour. This is a parameter that MPEmbed used to use (still supported, but it’s deprecated — and has been replaced).
In order to fix this problem, MPEmbed is now ignoring visible Mattertags. Only hidden ones will be used for parameters.
