Meta tags are present on the site and working properly with images on Facebook and LinkedIn.
But when I try to test my pages, its giving me ‘No metatags found’ error. It contains image and all twitter card content.
Site URL: http://ph.parker.com/us/en/quick-couplings-hydraulic-up-to-6700-psi-st-series-couplers

Content-Type: text/html is also present on the page.

User-agent: Twitterbot is allowed in robots.txt

Any solution??
