Or, another option is to set uri handling to default in wordpress and stick with the example.com/?json=1, etc, etc approach.
Alright. I believe I’ve found the answer to my dilema here.
I have wordpress installed in a directory underneath the main domain aka: wilfordwelch.com/wordpressinstall. I had created a page under the main domain (wilfordwelch.com/blog_titles) which was outside of the wordpress system. But I was using javascript to call into wordpressinstall.
Apparently, a fit is thrown when this happens. Apparently, if your going to make json requests you must be within the same directory. The exception, I assume, is if you use jsonp with a callback.
