Twitter cards not working. Validator returns 'Internal Server Error'


#1

Seems like reading through these forums this is a common problem, though I have yet to see any tips on resolution.

When first setting up two sites a month ago I got my twitter cards approved & the validator worked. Now when I try any url from either site in the validator it returns “unable to render card preview”, with ‘Error: Internal Server Error’ in the log section below. My posts - likewise - are not being ‘twitter carded’. No summary section, etc.

Any clue? This is frustrating. Been trying to get the validator to work for 2 days now.

I see now my twitter cards are showing up. But the validator continues to fail.

I have the same problem and no one has offered a solution.
