    Have you tried removing wp-includes/classes.php and re-uploading the copy from the installation files? Often an error generated by one of the core files after an upgrade means the file did not get updated properly.

    Yes I did, that too..

    reinstalled wp, disabled plugins, restored to original theme but still getting same problem

    Then a look at the underlying code here may help. At those lines in classes.php preg_match() is part of the internal rewrites for permalinks. I’m not all that adept at working with WordPress’ rewriting scheme, but:

    What is the permalink structure you are using on the blog? If you reset the structure to default (temporarily), does the error remain?

    I am using custom option and here is it..
    /%category%/%post_id%/%postname%.html

    everything was working smooth.. before update..

    I deleted permalinks and changed to default it works.. so it means i can not use the custom permalinks? Please notice this bug

    This is NOT a bug. I applied exactly the same permalink structure as you posted above – and it works. It must be your server or something else interfering with it.

    moshu.. how is it possible all default are working fine but not the custom one?

    I don’t know. On some servers including the %category% just doesn’t work…

    If it *was* working but after your update to 2.3.1 it no longer is, you can certainly file a bug report to notify the developers:

    http://trac.ww.wp.xz.cn/

    Be as detailed as possible in reporting it. You might also reference this thread.
