i was installing facebook comment plugin in my website. But it says the url is unreachable . I have used noah classified website. whenever i have to share the item in it, the facebook turns into other kinds of link For eg www.noahclassified.com/index.php?item/31 [Broken] turns into www.noahclassified.com/index.php?item%2F31 [Broken]. So when i looked developers tool, it says the webpage have to include og:url, which i have done. Please help me to fix this problem because without this the site cannot be shared in facebook. Thank you for your time to read my problem, hope you will help me.
