Dear Srini & Friends
I updated to 1.5 and then my random quote stopped appearing on my main page. Reverting back to 1.4.4 seemed to solve the problem.
Then I updated to 1.5.1 today and my random quote stopped appearing again, so I reverted to 1.4.4.
I'm running WordPress 3.1.4.
This isn't a big issue, but I'm curious about what the cause of the problem and its solution.
