I have wp v3.5 currently installed, and as mentioned in an earlier post, randomly WP would throw a 302 redirect to the front page. After de-activating all the plugins and enabling them one by one, it turned out that WP Super Cache was causing this issue. I tried both mod_rewrite and PHP mode in caching, but same results.
The plugins currently installed are:
Advanced Custom Fields 220.127.116.11 All in One SEO Pack 18.104.22.168 BackUpWordPress 2.1.3 Disqus Comment System 2.74 Fanciest Author Box 1.3.3 FancyBox for WordPress 3.0.2 Google News Sitemap 1.0.9 Google XML Sitemaps 3.2.9 Quform Form Builder 1.3.6 SlideDeck 2 Personal 2.1.20130116 WP Ajax Grid 1.2 WP Minify 1.2.0 WP Pro Ad System 2.3 WP Super Cache 1.2
The response header:
