The "htaccess" error with code 301 or 302 will be showing when domain name of your website was set to redirect.
You can check if it's set to redirect in cPanel File Manager
/home//.htaccess
/home//public_html/.htaccess
Sample if it was set to redirect:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^olddomain.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.olddomain.com [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [L,R=301,NC]
RewriteCond %{HTTP_HOST} ^olddomain.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.olddomain.com [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [L,R=301,NC]
Solution
1. Comment redirect line in .htaccess file.
2. Access to RVsitebuilder 7 to edit your website again.
