This is pretty simple. Upgrade your version to wordpress 2.6, and that’s fix your problem. I wrote about this issue before and apparently it was fixed once it upgraded without I noticing that it has been fixed. I must say that this is rare problem, since only small number of blogs having this problem once the upgrade, and blogjer is one of them.

I notice few blogs still having index.php on its URL, where some of them I have personally mail them to remove it since you no longer need index.php to make your wordpress page works. It looks ugly though.

In case you never experienced this before, this is what I mention above
