I was having some trouble with the CDN tax receipt extension, so I uninstalled the extension. When I tried to reinstall, I got this error message:

Sorry but we are not able to provide this at the moment. Field: name must be unique. An conflicting entity already exists - id: 99 Return to home page.


  • How did you uninstall the extension? Did you do it through the extension screen or through the file system? I'm thinking when you uninstalled it, it left some stuff in the database which is causing conflict when you're reinstalling. – Jade Jan 17 at 12:18
  • Is there any associated errors in the Civicrm Error log? There is a handy log viewer extension here: civicrm.org/extensions/civicrm-log-viewer – Luke Stewart Jan 24 at 23:16
