As you know that I faced some problem especially missed schedule posts issues after upgrading to WordPress version 2.9 last month. However, I managed to find the solution in the internet and the miss schedule posts problem had been fixed. Today, I saw the newest WordPress 2.9.1 released by WordPress developer team and the main purpose of this release is to fix some known problem caused by WordPress version 2.9 such as miss scheduled posts and pingbacks.
Just for your info, I’ve just upgraded to version 2.9.1 and I hope the miss schedule posts issues will be solved permanently. Therefore, if you had experienced the same problem like me, you may proceed to upgrade to version 2.9.1. Go to Tools -> Upgrade and upgrade automatically within your blog’s admin area. Thanks to the WordPress developer team for their effort to build a better blogging platform for us.
