Hi! I am using Jetpack for the share to social media icons at the end of each page and posts. When I share a post, it shows the featured image on Facebook, no problem. But when sharing the main page, that also have a features image, it comes with a white frame (no picture) when shared in Facebook. Any suggestion to correct this deeply appreciated!
Hi @zoetropo,
I hope you are well today and thank you for your question.
You can use the following Yoast SEO plugin that will generate facebook open graph tags for home page.
After using and configuring the plugin please use this tool Sharing Debugger - Facebook for Developers to delete your site cache from facebook.
Best Regards,
