Recently got this message: "Your calendar theme has been switched to Vortex due to a rendering problem. For more information, please enable debug mode by adding this line to your WordPress wp-config.php file:
define( 'AI1EC_DEBUG', true );"
I tried to debug but it's not working, site goes blank when I add that line.
Not sure why my calendar theme stopped working, it was fine.
Any help is appreciated.
