I didn’t have any problem until approximately 2 weeks ago. Now I feel I’m getting the run around. I contacted GoDaddy & they checked what you suggested about the CDN & it didn’t work. When I told them that it might be a robots.txt restriction as you stated this was their reply, “We cannot check the file on our end it might be in the yoast seo plugin”. Need help! Can it have to do with the update cause that’s the only thing done in the last 2 weeks that changed on my site?
