Invalid json data on WordCamp JSON API

[miyauchi]

The response of wp-json has a following line at the end of file.

<!-- Page not cached by WP Super Cache. No closing HTML tag. Check your theme. -->

Example:
​https://2016.kansai.wordcamp.org/wp-json/
​https://2016.kansai.wordcamp.org/wp-json/posts/

It seems that it is caused by WP Super Cache.

Thanks!

It will be fixed by adding $wp_super_cache_debug = false; to somewhere, but I haven't tried yet.

I sent a pull request to WP Super Cache.

We have some custom code to make WPSC play nice with the API^1,2, but some of it was disabled for troubleshooting, which caused this error.

It's fixed now, thanks for pointing it out :)
