Error Button Coupon Do Not Work Then Minify CSS HTML JS by CloudFlare

My website has speed slow loading, so I went to the solution with CloudFlare. In Speed, they have CSS, HTML, JS Minify. After I used that function, the site load speed was improved, but CSS and JS were faulty.
Specifically, I can not click on the button – “Click to Reveal” on the Coupon Site.
And slide on top also does not work.
After I change the form of Website Coupon -> Deals & Offer – works normally!
==> Button and Slide Errors.
(I turned off CloudFlare at the time of the error, but it seems that the Css & JS file has been saved on the host)
If anyone has ever experienced this error please help me fix them?
