error while editing views
jQuery Update has some problems with v1.8.7 currently (related to the version of jQuery UI included); downgrading to v1.7 should fix the problem.

See these issues on D.o for more information:


Suddenly stopped working - TypeError: c.curCSS is not a function
Update jQuery UI to 1.8.24


The reason your View isn't working is simply that the Javascript error is preventing the relevant events from being attached to the elements. So when you click a link, instead of Views loading the JSON via AJAX and processing it, you're instead forwarded to the JSON page itself.
