Just Product is posted

Pages will not post but blogs post or other CPTs should post.
Please check if you have a standard featured image with your blog post or news post. Image should be at your own site. No remote images or images with URL will work.
Without featured image, it will not post.

Send any link which is not posting.

Regards

Dear Qamar
Thank you for your reply
Be sure that images are at my own site.
About standard featured images I don’t know what do you mean.All the page either products featured images or blog featured images are same but their dimensions may defer.
This is URL of one of blog pages.
Regards,

sorry I forgot URL.
It is https://gigamallco.ir/%d9%85%d8%ad%db%8c%d8%b7-%d8%b2%db%8c%d8%b3%d8%aa-%d8%ae%d9%88%d8%af%d9%85%d8%a7%d9%86-%d8%b1%d8%a7-%d8%af%d8%b1%db%8c%d8%a7%d8%a8%db%8c%d9%85/

Well the issue looks in the URL of the post as it has RTL language but your products URL is fine.

We will test this URL and then let you know if Instagram accepts it or not.

Dear Qamar,
