Recently I broke ties with WordPress and migrated all of my site's content to my own custom-made CMS. All works great except for one thing. All previous links to my site's blog posts have a trailing slash. Since none of my current URLs have a trailing slash, the previous links no longer work and my SEO is nearly non-existent. I've been attempting to find an htaccess rule that will redirect all trailing slash URLs to URLs with no trailing slash, but as of now, nothing works.
Use this redirect rule as your very first rule to remove trailing slash:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ /$1 [NE,R=301,L]
