I'm helping my brother put together a WP based members area and after it was protected, some strange things started happening. The first was the menu nav just totally disappeared out of the blue. Had to build it again. Then sometimes when permissions are changed, thumbs stop showing and you can't get them back no matter what. You have to delete and remake the entire post.

I told him to scrap it and use another CMS because it's one small headache after another, playing whack-a-mole with little glitches. Though I'm curious as to what issues you've had. I never gave the internal cron any thought until I read your post.
