Recently, posts in our scheduled queue have been going up before their scheduled time. Today, I've had about three different posts scheduled for the 14th go up on the published blog at the times they are scheduled for on the 14th (so, a post scheduled for 13:00 on Sept. 14th went up at 1:00 PM today). I checked the date and time in our Settings, and they are correct (Sept. 9th). This has been happening very frequently recently (at least one post a day goes up early), and is somewhat detrimental to our blog.
We have the following plug-ins active:
All in One SEO Pack
Google XML Sitemaps
Thanks for any help.
