My hosting provider uses cdn services which I don't have control over.

Attached is a screenshot of how my dashboard looks like now after the upgrade. Any ideas on how to fix this?

For instance when an order is placed, I do get notified automatically by email. However, when I attempt to view the message using Windows default mail app, it keeps loading endlessly without displaying anything. I've also tried viewing the message directly on my browser by logging into my email account. Interestingly, it shows on the browser, but in an unreadable format, as shown on the screenshot attached. Kindly advise.
