However, in Opera 9.26, I got a JavaScript error indicating that the JSON was not valid.

Strangely, I could not find anything on their bug tracker indicating that such a problem (JSON and Opera) had been fixed.<\/p>\n<p>What was even more interesting was that <a href=\"http:\/\/www.opera.com\/download\/\">upgrading to Opera 9.50<\/a> also solved the problem independently; that is, things worked fine even with the older version of jQuery.  This goes to show the importance of keeping your software up to date and highlights the complicated interactions between different browsers and client-side code in a web application. <\/p>","protected":false},"excerpt":{"rendered":"<p>I ran into a weird problem while testing one of my sites that used jQuery with Opera 9.26.
