Problems after installing Imagify

Hello,
After installing Imagify, I have some troubles on my website especialy about the portfolio-type witch are my main menus (Projets, concours..).
My theme is Virtue from Kadence Theme.
Their support tell me :
“Looks like you have a minfy plugin, loading minified css in its own file: https://vimade.ch/wp-content/cache/wpfc-minified/fcf43a02b3e057a358e884a4cf4d5cb0/1518350851index.css
That is great but it’s not been updated to match that of the latest css.”

So please could you help me to fix that issues quickly ?
Thank you very much for your help !
