Hello!
I have samekind of problem although not exactly. The error I get is: “Import comment: Error validating access token: Session has expired at unix time xxx current time is xxxyyy”.
I haven’t changed my Facebook password. This problem appeared just recently and I haven’t slightest idea where the error came from. I haven’t made any changes to my Facebook account or app or to WordPress settings.
Our site is https://www.goodkind.fi
I appreciate if you have any advice how to move on.
Thanks!
