Hi @mushlih,
When your date archive setting is set to ‘disabled’, we redirect date archive pages such as /2020/09/ so they don’t work anymore.
Yes you can enable date/author archives but still make them not to appear in Google search results. Then you need to use Enable on the author/date archive and set the ‘Show author archives in search results?’ option to No.
As explained earlier, if your posts are already using categories/tags, there is not much benefit to have extra pages such as date or author archives that also list the same posts. It depends on your content and what is best for your readers. If you have a good structure with categories/tags, that is just fine.
