Odd Behavior

Hi Guys, I am having a ton of errors in my logs still and no one has addressed it, and unfortunately, now I am getting odd behavior on the website. If I go to the site with the fully qualified name, it works, no issue. If I go to my site without the www in front I get a black screen. I noticed this in the URL where SWIFT redirects.

I even tried to redirect in .htaccess, and still, it does not work.

https://www. domain .com/wp-content/cache/swift-performance/domain.com/desktop/unauthenticated/index.html

I can no longer access my domain without the www in front. I have not changed any DNS settings since I set the site up 6 months ago, but I am seeing more and more errors in my logs from swift. I really need some help to know what is going on.

Another odd thing is that now when I try to go to the dashboard it is taking 60 seconds or longer at times.

Here are some of the error that is repeated quite a bit in the logs.
