Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
We’ve covered the basics of minification with the W3 Total cache plugin. You may check that from here:
https://mythemeshop.com/blog/w3-total-cache-tutorial/#general-section-minify
I understand how hard someone needs to work on their site. So, before you minify CSS files on your site, I’d recommend that you first test out these changes on a testing/staging environment and then push them to your live website. Or create a complete backup before applying them.
For further assistance with CSS minification, get in touch with your theme provider/W3 Total Cache support, as they’d be in a better position to assist you with further inquiries.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
