First off, I would like to apologise to all our visitior for the long downtime (partial) of our site on Dec 30, 9.00 AM PST to Dec 31, 2.15 PM PST. During this time, if you’ve visited he site, and tried to view a post in a single mode or any other site page, you may’ve noticed that your request was redirected to our home page. This was casued by the following mod_rewrite rule, which I had implemented on Dec 30 at 9.00 AM PST, redirecting all the requests back to our home page. After adding the rule, I had only checked our main page, and didn’t look single post and other WordPress pages.
rewriteRule ^index\.(php|html|htm|asp|aspx) / [R=permanent,L]
Lesson learned, whenever, you implement something new, it’s always better to test all possible paths.
