I've got a Wordpress website and that i want for instance this URL:

http://mywebsite.com/tag/hola

to redirect instantly to

http://mywebsite.com/tag/hola/

However , i could not place the trailing slash there. Could somebody assist me to? Can there be something I possibly could use my htaccess to instantly redirect it? Thank you plenty!
