Just a few minutes ago, I was wondering where to set up ogp on nicepage, but I tried it.

Edit with Nicepage> Right block> SEO and Head> Page settings> HTML> Additional head HTML

Upload the optimized image to the server first as specified by OGP,
the script conforming to the OGP rules was saved in the "Additional head HTML" above.

After a few minutes lag, the new OGP was recognized by Facebook Debugger.
This time, the page I created successfully with the Wordpress plugin.
Thank you.
