Well..
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”.
Refresh the site and then its back to normal again.
Reason i was doing this was, because when the error occured, i even could not accessing my wp-admin site.
So, by creating the temporary tables and field on the database, i could logged in and disable the plugin that affecting the site.
Thanks,
Denie
