edited htaccess file now Blog isn’t working.

I edited my .htaccess file in the root directory as my site could be found with either https://www.pcenclosures-direct.com or just pcenclosures-direct.com. I was told the edited .htaccess file would resolve this by redirecting to https://www.pcenclosures-direct.com

Now my blog was on pcenclosures-direct.com/pcenclosures/ and I am getting the following error:

Redirect Loop
Redirection limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.

The browser has stopped trying to retrieve the requested item. The site is redirecting the request in a way that will never complete.
* Have you disabled or blocked cookies required by this site?
* NOTE: If accepting the site’s cookies does not resolve the problem, it is probably a server configuration issue and not your computer.

Can anyone tell me how I can resolve this so when anyone goes to my blog https://www.pcenclosures-direct.com/pcenclosures/ it works.
