Hello again!
I think Google noticed your site to be offline, so they may have deindexed you–if only temporarily. See the tweet below for an official statement on that this shouldn’t further affect you.

In any case, only via Google’s Search Console, you can assert the indexing state of your pages–because that isn’t tied to your Google Search-fingerprint. Google profiles you to give you more relevant results you may be more interested in. For instance, when you search for “pizza,” you may see the opening hours of a pizza delivery service nearby.
So, keep an eye on your ranking at the Search Console, notice which changes may affect the average positioning over time.
As for the sitemap, do compare yours with the one from our site (https://theseoframework.com/sitemap.xml)… do they look the same? When they don’t, then there may be sitemap issues. Check the sitemap settings at the bottom of the SEO Settings page. There, you may find warnings indicating problems.
As for other indexing issues, the theme or another plugin may output extraneous robots directives. Again, this is something I can’t inspect without a URL.
Lastly, your WordPress site may discourage indexing. The SEO Bar (found on your post overview pages) should indicate common indexing issues under the “I”.
I hope this helps! Again, best of luck with your endeavors! Cheers ??
