Weird subdomain problem

One of my clients is having a weird subdomain problem. The account has 5 subdomains, but one of them isn't redirecting correctly. The subdomain is ang.mydomain.com but it's redirecting to www.mydomain.com/ang/

(To be clear, the folder is correct, but we don't want the URL to be www.mydomain.com/ang/)

I've tried removing and resetting the subdomain, but that didn't fix the problem. The DNS zone in WHM looks fine.

Any ideas? Thanks in advance for your help.

 

They're using my nameservers. I manage their account for them. All 5 subdomains were set up through an account-level cPanel interface. It's been a few months since I set up the subdomain in question, so I can't remember if there were any errors when it was first set up (the subdomain is only now being used).

 

That was it! Sort of.

It turns out that all of the other subdomains had an .htaccess file except that one. I'm not exactly sure why not having one would cause this problem, but since it's working now I'm not going to worry about it. Thank you for your help!

(BTW, for anyone else with this problem, don't forget to clear your local DNS cache after making the change. At first I thought the solution hadn't worked until I remembered to clear the cache.)
