Try clearing your DNS cache if your domain seems to be acting weird (V1)

If you have your domain setup correctly and pointing to your 22Slides website, then later notice it pointing back to your old website or domain registrar placeholder page, this is likely to be an issue with your DNS caching.

Much like how your computer saves files from websites for later, it also sometimes saves the location domain names point to, so it doesn’t have to look it up every time you visit the website.

Clearing your DNS cache my fix the issue.
