Hi - Ive published approx 153 blog Newsletters since 2018...I've shared links to each on social media and in emails to my site members - all has been working fine.
HOWEVER, about 10 days ago I published my latest Newsletter, and any link to it I send to any forum (or if I email that link to anyone) returns a 404 error code...see: https://www.birdingbob.com/post/nyc-cardinals-chocolate-snow-and-the-weather-the-weather
On the other hand, the link to my blog Newsletter itself works just fine: https://www.birdingbob.com/sightings
In fact, links to all my previous Newsletters (blog posts) that had worked fine, all return 404 error codes now..in other words, each link to the 153 prior blog (Newsletter) posts worked fine until 10 days ago...now every one is a broken link (404 error code).
Can someone please help me? I have not changed anything on my site except add a blog post 10 days ago...so something is going on behind the scenes that I am unaware of and have no control over.
