Has anyone figured out what the solution is on this? We were on GoDaddy managed wordpress (recently moved to a VPS hoping it would help) and after a wordpress update we started getting this error. It only seems to happen with our site’s purchased theme (Newspaper).
Another symptom is that we can’t set menu locations so we are unable to add a menu to our site. It used to all work…
GoDaddy knows nothing about this error.
