The current version of SmaCrawl has a problem. I don't know if because of update from 2.2.6 to 2.3.0 or because the update to WordPress 5.2.
The google preview is not the one of the post or page but the main page of the site. This happened before when the update to WP 5.1.
The fact is that in other site (xgintarcadegames.com) that I didn't update to WP 5.2 nor SC 2.3.0 it is working ok.
The problems is not only in this site, also in discoveringtheworld.me that is also updated in WP and SC.
I cannot understand that every time there is a new WP version there is problems with this plugin (and with others by the way, like Hummingbird).
Please check it and let me know how to proceed.
You have granted access to support (because of another problem not yet solved). But don't change anything in the main site xgint.com (it's a production site). You can change anything in the rest of subsites.
