Our Cloudflare CDN service is very unstable recently and cause our website can not work. We have paid $250 to upgrade the plan from Pro to Business Plan. It seems no issue now. Not sure if it's the root cause, if you meet the issue again, please report to us. You may need to clean the browser cache to invalide the dirty cache in the browser.
