    I know this one is not good solution. But, what i tried was creating new tables “wp_categories”, and also created 1 db field called “cat_name”.

    So, by creating the temporary tables and field on the database, i could logged in and disable the plugin that affecting the site.


    so what IS the new name for wp_categories? Since the default category widget isn’t XHTML compliant (boooooooooooo) I’m using a plugin.
