I'm using Simple SEO 0.4.8 - and without any changes...in the last week a lot of the pages show up "Page Cannot Be Found".
I can't replicate the issue although it has happened to me once. I'm getting a lot of members on the site with the same issue and I don't even know where to start on troubleshooting the issue.
Here is the thread on our site with this problem:

Any help would be greatly appreciated, thanks!
