Hi All I am getting multiple ewrrors on a website that had been working for over a year prior to my host upgrading their PHP.

Now I am getting the following errors in the dashboard and the page that I have a calender in is displaying:

parameter 2 to be string, array given in /home/avpzjhv/public_html/westdripfarm.com/packages/calendar/blocks/calendar/controller.php on line 28

Warning: explode() expects parameter 2 to be string, array given in /home/avpzjhv/public_html/westdripfarm.com/packages/calendar/blocks/calendar/controller.php on line 28

Warning: Cannot modify header information - headers already sent by (output started at /home/avpzjhv/public_html/westdripfarm.com/packages/calendar/blocks/calendar/controller.php:28) in /home/avpzjhv/public_html/westdripfarm.com/updates/concrete5.4.1.1/concrete/libraries/view.php on line 764

Can anyone help?

Kind regards
Paul
