Where are these 404 responses in Yandex Webmaster?

Good time of day.
The last few days Yandex.The webmaster reports that yesterday on my website was 0 pages with a 200 response and 60+ with a 404 response.
Of course I was interested in what was going on and saw the following picture:
I want to see what pages of my site at all and there never was.
Where did they come from? Yandex? Wordpress? Cloudflare? Viruses? Some questions.

Encountered someone else with this crap?
Examples of pages:

On the second site, which is on the same hosting the same crap, just links to another view:
And so on.
Second, by the way, without Cloudflare, but they're both on WP, where it links Jumla - I have no idea.

Encountered anyone similar and what would you recommend to take?

Look in the direction of the site map
I understand reg1.php form of registration?
If so, why do you want it to index? - lolita41 commented on June 8th 19 at 16:49
Do found that map module of the site required updating.
On one site updated, the second has not yet become.
There is a site map open at sitemap.xml open the inscription:
Error loading stylesheet: an unknown error has Occurred (805303f4)https:// blah blah blah /wp-content/plugins/google-sitemap-plugin/sitemap.xsl

See if the problems recur at the site where I have updated the plugin. - Carlee_Lo commented on June 8th 19 at 16:52
in fact of the matter is that my site does not provide any form of registration. - Carlee_Lo commented on June 8th 19 at 16:55
and then for the file reg1.php? - lolita41 commented on June 8th 19 at 16:58
