# Plugin Development: Settings with Checkboxes

 * Hi,
 * I’ve googled a lot but I just can’t see the error in my code.
    I am developing
   a plugin that has two options with checkboxes, “remove_comment_ips” and “show_branding”.
   However, I cannot disable the checkboxes in the settings – after saving, they
   become enabled again.
 * Any hint on what I am missing here would be appreciated 🙂
 * This is the (reduced) code of my plugin:
 *     ```
