Please note that you do NOT want to use any “redirection” tools from Namecheap. The easiest way to link your domain to our hosting is by changing your domain’s nameservers. If you have reasons to do so, you can also keep using Namecheap’s DNS, and setup DNS records to point your domain to our servers, but that’s more involved.
Just don’t use any redirect or URL masking features to try and use your domain name with our hosting. They don’t work well.
