 * Hi Peter,
 * During my trials to define the best workflow to establish new entries in my music
   database(s), I tried to avoid that the plugin generates new unwanted entries 
   in one of the child tables by defining a certain column as unique.
    It works 
   fine (result is fine), however, a failure message occurred, most probably because
   the plugin could not pass a message.
 * See the failure message below.
 * Thanks and best regards
 * Michael
 * **Here‘s the failure message:**
 * Fatal error: Uncaught Error: Class ‘WPDataProjects\Parent_Child\WPDA_Message_Box’

 * Superb ;-), Peter!
 * Did you already patch the download version or when do you expect the next version
   arriving (hopefully as well with the **order by in projects**…)?
 * Best regards

 * Hi Michael,
 * I uploaded the patch. You need to delete the plugin and then reinstall it.
 * Make sure you’re not losing your work! Before you delete the plugin:
    – Go to
   the Settings menu – Click submenu WP Data Access – Click tab Uninstall – Uncheck
   both checkboxes
 * Best regards,
    Peter
