Andrew, thank you for you reply.
sorry, I thought I was posting in the correct forum, my bad.
tim.
On my site, under advance featues, in the control panel it has an option to “lockdown” wordpress, you cannot do updates while in lockdown mode.
I have mine on auto lockdown so that when I turn off lockdown, lockdown mode re-enables after a pre-determined time.
hope this helps someone.
FYI: this is still an issue in vesion 4.6.1.
My install is out-of-the-box fresh and only using theme Twenty Fourteen and bbPress.
I commented out the code indicated from Julian and it now works great.
