"Author" and "updated" missing in pages structured data

Hi, I've found that, in the structured data menu of google search console, there are "author" and "updated" errors (both are missing) for pages only, while posts are ok because they have these data. I've found some info about the problem here: https://kb.yoast.com/kb/fixing-hcard-author-error/ Thank you for your great support, regards Francesco http://www.warm-mastering.com/
