I have not had schedules work for 2 weeks. Nothing suggested has made a difference. I too have spent time chatting with GoDaddy with the same result. The additional plugins I’m using are as follows:
Akismet Version 3.2 | By Automattic
Module Control for Jetpack Version 1.4.2
WordPress Editorial Calendar Version 3.6.2
WordPress Importer Version 0.6.3
I am using the Creative Blog Version: 1.0.1 theme.
