Initially I was not a great fan of WP Super Cache. The reason was that I keep on changing theme design and files on regular basis. With WP Super Cache plugin the changes are not reflected immediately and after every change you have to flush out the cache to see the changes.
However it does bring a great benefit for heavy traffic website when your blog slows down.
Yesterday I upgraded Indian Recipes blog to WordPress 3.1.2 and observed that WP Super Cache doesn’t work.
However all of sudden it started to work today. I was not sure what went wrong. There was no upgrade for WP Super Cache plugin either.
