Event Categories not working – warning / error message

Hi,

After setting up events and selecting a category for each event, i save the event, but when i come back to event options for each event the following error message happens:

—-
Event Categories ?

Warning: in_array() expects parameter 2 to be array, string given in /home/kirk007/public_html/wp-content/plugins/event-registration/event/evr_event_edit.php on line 124

—–

If i save with category checked i get another error message saying:
“there was an error in your submission, please try again…”

If i edit event again and save without checking any event categories it will save and work fine (without using any event categories feature)

thanks
kirk
