Type options.php into your address bar (
example.com/wp-admin/options.php) and you’ll get this alphabetized listing of all the options stored in your
wp_options database table. Some won’t be editable — if they’re stored as arrays, you’ll just see “Serialized data” — but the rest can be changed here.
If you’re familiar with PHP arrays, you can edit those serialized options by changing the database fields directly. Copy the serialized array (shown here in the row with the ID 10390) and paste it into the Online PHP Unserializer at blog.tanist.co.uk.
This tool will convert the serialized array to a more familiar array printout. You can then make changes and re-serialize the array to store it back in the database.
With great power comes great responsibility. Be very careful with this! And consider backing up your database before you tinker.
