While attempting to post comments to an individual blog post, I've noticed that a there is a request to load the following file: /etc/clientcontext/default/content/jcr:content/stores.init.js?path=[path of current page]. However, this file results in a 500 error. What is this file and why is it being loaded on the page? Also, how can I troubleshoot 500 errors for content under /etc/clientcontext?
