wpsnoop: Origins of the WordPress database table "wp_wiziq_wclasses"
WordPress is comprised of many database tables and many plugins and themes operate without needing to create new tables. When asked where did the table wp_wiziq_wclasses come from?
This page provides some information on the wp_wiziq_wclasses table and a list of plugins and themes where it may have originally come from.
Can the wp_wiziq_wclasses table be deleted safely?Maybe. It depends on your situation: If you are sure that you no longer use the plugin or theme that created the wp_wiziq_wclasses table you can certainly delete it with phpMyAdmin BUT we would suggest renaming the table to something else like old-wp_wiziq_wclasses and make sure your WordPress installation still works :)
Assuming everything seems ok after renaming the table you can safely DROP old-wp_wiziq_wclasses and carry on.
Remember that backups are your friend so make them often and if necessary consider hiring a professional to assist you.
