After activating "Browser caching" & "BWP Minify" slideshow is not working

After testing my website on pagespeed, one of the recommendation was to activate leverage browser caching by adding these lines on the “.htaccess” file :

<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>

Another recommendation was also to minimize CSS and JS script, so I installed the “BWP Minify”.

I don’t know if it’s the plugin or the cache activation but since slideshow is not working anymore.
It works when I visit the website for the 1st time, and after some times the slides don’t show.
If I clear the browser cache, or open a private tab, the slideshow appears again.

I also tried to use the “WP Super Cache” plugin, but I get the same issue.

Thanks.
