Fatal Error in Scheduler 2.3

after updating to version 2.3 I receive the following error:

Fatal error: Cannot redeclare create_options() (previously declared in /customers/diefechis.de/diefechis.de/httpd.www/wp-content/plugins/dmsguestbook/admin.php:3489) in /customers/diefechis.de/diefechis.de/httpd.www/wp-content/plugins/event-calendar-scheduler/scheduler.php on line 338

It seems that there is a problem with the guestbook-plugin. How can i fix this problem? Will be there any update? When using version 2.0 of event calendar no error occurs an both plugins are working…

Note: The Error also occurs using WordPress 3.0.x


It seems both plugins are using same ‘create_options’ function.
Open wordpress/wp-content/plugins/event-calendar-scheduler/scheduler.php file.
And replace all ‘create_options’ strings with ‘create_options_evs’.

Best regards,

Thank you, my problem is solved!
