After realizing the fact that the problem might have the same roots with unsuccessful attempts of saving theme settings, I checked the /wp-admin/admin-ajax.php file and surprisingly found out that the file was renamed as admin-ajax.php_. After fixing the name, the problem got resolved.
Thanks a lot for the guidance!
I wrote to Yoast’s support team as well and they simply suggested me to use the Facebook object debugger if I face the same problem ever again. However, it can easily become a headache if anyone has to do this manually for all pages/posts.
How does your modification to the child theme’s function.php help resolve this issue @dude? Does it somehow automize the process?
Thank you for your reply @dianado.
I am having the same issue with the latest version of Yoast SEO Premium and Enfold. Did you somehow luckily resolve the issue @dianado?
I am providing the admin console details in the private content section for the moderators to have a look at the issue for my website as well.
Thank you for your help.
