 * Hi, after I changed hosting server, when I open Google Calendar Settings it happens
   to spit an error:
 * “Fatal error: Uncaught Error: Call to undefined method Google_Client::getClassConfig()
   in /trychologia-slask/wp-content/plugins/appointments/includes/external/google/
   Logger/Abstract.php:126 Stack trace: #0 /trychologia-slask/wp-content/plugins/

 * For more, same happens when I try to remove bookings, and when I book on front
   page it keeps showing the loading icon, but no reservation confirmation notice
   shows up.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fgoogle-calendar-api-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello [@pauron](https://wordpress.org/support/users/pauron/)
 * Hope you’re well!
 * I could not replicate the issue on my end. After Migration some Appointments 
   files may not be moved, please try re-installing the plugin via FTP. Download
   a fresh copy and upload the folder to `/wp-content/plugins/` by replacing the
   old one.
 * If the issue will persist after this, please run a test for a conflict with another
   plugin. Deactivate all other plugins and see if the error still appears.
 * If everything is well, activate one plugin at a time to find the one that causes
   this.
 * Let us know how it went!
 * Cheers,
    Nastia

 * Thank you,
 * **WD Google Analytics** plugin made a conflict, after deactivating it everything
   seems to be alright. Thank you once again.
