I upgraded to 2.3.1 from 2.2 on Dec. 8. Shortly thereafter, I started seeing a sudden change and upswing in Googles report of pages blocked by robots.txt for my site http://www.livingtantra.net.
I have the wordpress native search available on my site. After NEVER seeing a single search results page appear in the google report, there are now 96 in the form of: http://www.livingtantra.net/page/2/?s=daoist.
I DO have a line in my robots.txt file: Disallow: /page/, but this has never before resulted in Google treating search result pages as potentially index-able.
Can anyone explain this?
