Simple File List Pro offers an extra tab within the Admin File List to give you access to some helpful troubleshooting and cleanup tools.
Reset the File Array
The plugin stores data about each file within an array stored in the WordPress database, such as descriptions, the date added and owner information. You can clear all of this data and reset the file list array by clicking this button. This can also be helpful if the file list is not loading properly.
Reset the File List Settings
Click this button in order to reset the list settings back to the original plugin settings. This can be helpful if you are having trouble with the list not functioning as it should. Also, remember to remove any shortcode attributes that are not needed to over-ride the settings.
Delete Orphaned Thumbnail Files
Delete thumbnails which have no associated image or video file. This can be helpful if you move files in, out and around outside of the plugin. Thumbnail images are stored in a hidden folder (.thumbnails/) within each list folder.
The Raw Outputs are displayed below the tools so you can see all of the data the plugin is using. This information can be very helpful for troubleshooting purposes.
