Can .htaccess be changed through FTP after it was edited in WordPress in a way that breaks the site?

Can .htaccess be changed through FTP after it was edited in WordPress in a way that breaks the site? - .htaccess files are extremely useful in many cases for users who either do not have root permissions or for users who simply aren't comfortable in making changes in their web server's configuration file. Trying to debug .htaccess not working isn't always the easiest thing to do, however, hopefully by checking the discuss below mentioned about seo, htaccess, redirects, ftp, .htaccess common problems as well as the troubleshooting tips, you'll have a better grasp on what you may have to modify to get your .htaccess file running smoothly.Problem :

I made the mistake of putting in the following code on my .htaccess file thru Yoast SEO:

# Remove www from any URLs that have them:
RewriteEngine on
RewriteCond %HTTP_HOST ^www.
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

Now there's an infinite loop and I can't access my WordPress dashboard anymore. Is it possible to access the .htaccess file thru an FTP client like FileZilla and remove the change?

Solution :

Absolutely. Your .htaccess file is located in the root directory of the website and can be accessed via FTP.

Additionally, if you would like to do some further testing, give the htaccess tester tool a try. It allows you to specify a certain URL as well as the rules you would like to include and then shows which rules were tested, which ones met the criteria, and which ones were executed.
