# Error since WordPress update

 * My calendar no longer is working since I updated wordpress. I have no idea how
   to fix it. As this is the plugin we are using I was hoping someone else knew 
   the answer.
 * Error message:
 * Fatal error: Cannot redeclare month_comparison() (previously declared in /var/
   sites/p/priestfield.org.uk/public_html/wp-content/plugins/calendar/calendar.php:
   2693) in /var/sites/p/priestfield.org.uk/public_html/wp-content/plugins/calendar/
   calendar.php on line 2693
 * I inherited this website from someone else and while I am happy to help I really
   know very little about things and I am totally out of my depth. Thank you for
   any help.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-since-wordpress-update%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Have you installed any other plugins recently? Or have any existing ones also
   been upgraded? This is a typical plugin conflict; keeping calendar enabled, disable
   your other plugins one by one, till the error on that page no longer appears.
   Then, let me know which plugin caused the issue. Thanks.
