Seems there might be an issue with the twitter scaper. Let me explain:
While Validating this url:
http://flim.me/@greenme (use “Twitterbot/1.0” User-Agent)
everything seems fine.
http://flim.me/@40tvfacts (also bot User-Agent)
the validator shows:
INFO: Page fetched successfully
WARN: No metatags found
But that is wrong. Use Chrome with “Twitterbot/1.0” User-Agent and you’ll see almost same info.
Now comes the strange part…
I found out that whenever I add a “ä”, “ö” or “ü” it works, while if it is missing the card wont render.
