In the process of searching for a solution to a very specific WordPress problem (getting the “Add Media” overlay to default to “none” for the link — no one I know ever wants it to default to inserting a link), I came upon a very useful general tip for WordPress.
WordPress stores a ton of settings in the wp_options data table. But a lot of those settings are not directly accessible for editing in WordPress admin. Or so I thought.
Turns out, it’s not linked anywhere in the admin interface, but if you have the Administrator role, you can access an All Settings page that allows you to edit any record in that table (except serialized data) by going to this URL:
http://YOUR_URL/wp-admin/options.php
Watch out… you have the potential to really mess things up here, which is why it’s not easier to get to. But it’s a handy way to easily update an option, if you know what you’re doing, without having to log into the database directly.
Oh… and if you want to fix the specific problem I was trying to solve at the beginning of this post, look for image_default_link_type and set it to “none”.
