wp plugin not working after website live

Please check the following

  • You have checked the URL of your WordPress installation
  • You have checked that your webhosting is compatible with uploading (file permissions, user rights)
  • You re-saved the permalinks (to make sure that URLs are used correctly)

Edit: This little amount of information gives us little space to work with. Also, please check that you have WP Debug set to true as it might provide you with information that you would normally not get.
