Hi David I’m having the same issue. Have you figured it out yet, if so please let me know.
The wp-config file last modification was 14 August 2014. That is around the time the website was created. I’m not aware of any version control being used. One thing I’ve noticed is SEO by Yoast plugin is installed on the sites that won’t update.. would that have anything to do with it? forgive me I’m new to this, obviously and have been thrown in the deepend so to speak, so learning on the fly.
I don’t think so.. how can I check if it has?
