Hi Rohitgparmar,
Debug has og:image tag, but don’t load it.
https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fstayread.com%2Fmore-than-325-cases-of-dengue-have-been-reported-in-ahmedabad%2F
Can You create a post with an image that has a name in English letters only for test? Maybe problem in the “અમદાવાદમાં-એક-મહિનામાં-ડેન્ગ્યુના-325થી-વધુ-કેસ-નોંધાયા” name?
In any case, this is not a problem with the theme, only with the plugin that displays this og:image tag or Facebook.
Best Regards,
TigriWeb Team
