Odd cards behavior


#1

I have implemented a twitter card with an open graph card few days ago.
I’m using pure php to fill content of the cards (for now content is 100% same on all pages).

The problem shows up when i try to validate cards (they are 100% identical on 4 webpages).
webpages list:

  1. http://taxijoker.com/
  2. http://taxijoker.com/m
  3. http://taxijoker.com/m/prices
  4. http://taxijoker.com/m/contacts
    contents of cards should vary only by language (preferred is Ukrainian)

In validator i can successfully validate pages 1 and 2. But i get an error on pages 3 and 4.

pages 1, 2 output:
INFO: Page fetched successfully
INFO: 16 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully

pages 3, 4 output:
INFO: Page fetched successfully
INFO: 16 metatags were found
INFO: twitter:card = summary_large_image tag found
ERROR: Required meta tag missing (twitter:text:description)
ERROR: Required meta tag missing (twitter:text:title)
WARN: Not whitelisted

hovever twitter:title and twitter:description meta tags are included on all pages =/

As far as I can see, the twitter:title and twitter:description tags are present, but with blank/empty values, on the last two pages.
