Ditto here...leary on upgrading to current version...alot of work
I just came back in after not being around over a year just to see if there was a fix or something for this error. Mine might have something to do with moving site from server to server using root access which should have kept all permissions intact.
Your's might be a permission prob. Not sure...not sure about my own...lol...
