问题
I'm facing an odd problem with my Leverage Browser Caching. In my .htaccess I use the following:
## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
## EXPIRES CACHING ##
This successfully caches my website. But the issue I'm facing is it is missing out some non-external JS files:
http://example.com/wp-content/themes/tracks/js/build/production.min.js?ver=4.7.2 (2 days)
http://example.com/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.4.1 (2 days)
http://example.com/wp-includes/js/jquery/jquery.js?ver=1.12.4 (2 days)
http://exmaple.com/wp-includes/js/wp-embed.min.js?ver=4.7.2 (2 days)
http://example.com/wp-includes/js/wp-emoji-release.min.js?ver=4.7.2 (2 days)
I tried to fix it by adding the following lines, but the result was still the same:
ExpiresByType text/javascript “access plus 1 month”
ExpiresByType application/javascript “access plus 1 month”
ExpiresByType application/json “access plus 1 month”
ExpiresByType application/x-javascript “access plus 1 month”
Any idea why it is not picking up the js?ver= and how to fix this problem? In case it helps:
Hosting: Hostinger
Server: Apache 2.4

OK, I managed to fix the issue. I was correct in using the following four lines:
ExpiresByType text/javascript “access plus 1 month”
ExpiresByType application/javascript “access plus 1 month”
ExpiresByType application/json “access plus 1 month”
ExpiresByType application/x-javascript “access plus 1 month”
However, the quotation marks around the access plus section are for some reason curly quotations. This was therefore returning 500 and 503 server errors. After replacing the quotation marks it has since fixed my issue and now correctly caches js?ver= files too.
My final Leverage Browser Caching code looks like this:
## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/json "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
