I'm having a server related problem with the events calendar. I developed a client site on my own server account using the plugin and it works perfectly. I copied all the files & database over to my client's server and now I can't create posts that use the events calendar.
Php shows the following error:
Fatal error: Call to undefined function filter_var() in /wp-content/plugins/the-events-calendar/the-events-calendar.class.php on line 884
The PHP version is 5.1.6 - will it solve this to change to version 5.3.x?
Thanks for reading :)
