  • For the first error see the sticky post on the main page of the forum!

    Thanks for the reply.

    I have read that topic but my WP 2.3 install was done over two weeks ago. I have the latest plugins such as Google XML Sitemaps 3.0 which works fine.

    My errors came after testing out the Permalink structure.

    I have tried => Date and name based option
    and left the Optional categories blank.

    I did note that each time I clicked on the Update Permalink that the screen goes white and show the following message:

    Fatal error: Call to undefined method WP_Rewrite::set_tag_base() in /home/beyblade/public_html/blog/wp-admin/options-permalink.php on line 81

    I haven’t changed anything else. Do you have any suggestions?

    Sounds like some corrupted (not completely uploaded) files during the upgrade…

    I have re-uploaded the file but there is no change. I’ve also reverted back to the Default Permalink but there are still errors.

    I have a back up but am not familiar with install instructions.

    Would you suggest I reinstall the previous back up?

    I would appreciate it if someone experienced could assist me with this.

    I reuploaded the wp-includes once more and EMPTIED my CACHE. Now things are back to normal.

    Thanks for your advice moshu
