Asif’s fix worked for me
I updated WP to 4.0.1 and Ai1ec to 2.1.8 and everything was working but..
I was getting blank pages for my event details. also was getting an error about the plug-in in the dashboard.. something about incorrect time_zone… (Bah, wish i got a screen shot of the error)
I tried the troubleshooting above, that didn’t work
undid that an did the update to the DB through phpMyAdmin.
all seems to be working fine now..
