Redirect 301 Used To Work, Now It Doesn't

[abigail]

My htaccess file works except the Redirects. They used to work.
sickle cell anemia is the one I added yesterday and it doesn't work.
back pain and heartburn used to work but now they don't.
sleep disorders and hemophilia are also in my cpanel Redirect and they work from there and are not really needed here.
But I don't want to do it through cpanel and I shouldn't have to.

Can you find what is wrong with my code?

Here is my entire htaccess file:
 

ErrorDocument 404 /404.shtml
ErrorDocument 400 /400.shtml
ErrorDocument 401 /401.shtml
ErrorDocument 403 /403.shtml
ErrorDocument 500 /500.shtml
# this is to handle the 301s because I moved my files or renamed them
<IfModule mod_rewrite.c>
    RewriteEngine On
# 
# Following is because linkback from: #ningxiebayinzi.com/unique-hemophilia-treatment-fixes-your-illness-prevents-hemophilia
Redirect 301 /hemophilia-treatment /unique/hemophilia-treatment
#
# Following is because linkback from: #solutionssnoring.org/brussels-griffon-snoring/
#solutionssnoring.org/ayurvedic-treatment-for-sleep-disorder/
#solutionssnoring.org/category/1/page/3/
Redirect 301 /sleep-disorders-treatment.php /unique/sleep-disorders-treatment
#
# Following is renaming by canonical when in home so .php needs to be specified
#Redirect 301 /sickle-cell-anemia-treatment /sickle-cell-anemia-treatment.php
#Redirect 301 /back-pain-treatment /back-pain-treatment.php
#Redirect 301 /hiccups-heartburn-treatment /hiccups-heartburn-treatment.php
</IfModule>

You have # in front of the ones that don't work. In .htaccess # is a comment, so those lines are commented out.

Well, that's embarrassing.
You are right and I even feel I have wasted your valuable time.
And the reason is cpanel didn't do the redirect and tech support was fixing it so that's why I had it commented out.
Thank you so much.

Happens to the best of us, Abigail! No problems at all. Glad it's working now.
