How to set browser cache to expire after one day?

Question

I'm using the code below in my .htaccess file to enable caching for my website:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
</IfModule>
## EXPIRES CACHING ##

In that code, you can see that the cache expiration time is set as 1 year for some file types and 1 month for others. What I need is to make it expire after a single day. I have already tried to replace it by "1 day" and "24 hours", but neither of those work.

It might be as simple as missing one keyword that is causing your issue.

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 day"
ExpiresByType image/jpeg "access plus 1 day"
ExpiresByType image/gif "access plus 1 day"
ExpiresByType image/png "access plus 1 day"
ExpiresByType text/css "access plus 1 day"
ExpiresByType application/pdf "access plus 1 day"
ExpiresByType text/x-javascript "access plus 1 day"
ExpiresByType application/x-shockwave-flash "access plus 1 day"
ExpiresByType image/x-icon "access plus 1 day"
ExpiresDefault "access plus 1 day"
</IfModule>
