Thank you. Can any anti-spam plugin be applied to the questions and answers? Or is the only defense moderation?

here is a screenshot of google structured data, it does not shows any error dude to missing entry-title, as I am using question and answer type. But I will try it once.

Yes question and answer are custom post, and comments are wp-comments.. only one extra table added is by AnsPress.

google didnt indexed page couse of these errors Error: Missing required field “entry-title”. Error: Missing required field “updated”. Error: Missing required hCard “author”. especialy Missing required field “entry-title”. thats becouse there is some thing wrong in the custom post type with entery title

Works ! but now i think need some change to css code (and in this im not good 🙁 ) http://loja1x2.altervista.org/anspress/

simply do this: download this manually: https://downloads.wordpress.org/plugin/anspress.zip, upload it to wp-content/plugins/ and then go to your wordpress admin -> plugins and activate AnsPress

fixed. 🙂 commit link

Give me access to your site, this is because missing html tag. check your theme for missing tag. we need to look at your site for diagnosis.
