As soon as I activate Ai1 1.22 on WP 3.1.4, any attempts to access the WP dashboard results in a blank page (completely blank, nothing loads at all). The site loads fine, just not anything in wp-admin/. I have tried flushing all settings related to Ai1 out of the database and the problem is still not resolved.
When I enable debugging on the site, the following warning and error appear:
Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of similar_text(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /sites/umcaspagsa/www/wp-content/plugins/all-in-one-event-calendar/app/helper/class-ai1ec-events-helper.php on line 831
