How to reset custom fields
Posterno includes a tool that allows you to reset all custom fields back to default. To reset custom fields, login into your site's admin panel and navigate to Tools -> Posterno tools -> Database. Here you will see the "reset custom fields" tool. Select the type of custom fields you wish to reset to start the reset process.
The reset process will happen in the background. The process will remove all fields installed onto your site and will then re-install the default fields. While the process is pending you'll see a notice in the admin panel informing you that the process is taking place. This can take a few minutes to complete depending on your server's resources.
Once the reset is complete, the notice in the admin panel, will disappear and your forms and fields will correctly display.
