I've come across this before and I know it's css caching but I can't, for the life of me, figure out how to fix it.
The theme I'm using is uDesign, which houses custom.css in a subfolder.
When I inspect element, it's pulling up a .css?ver=1.0 and no changes I'm making to the actual CSS are updating on the site.
Can anyone help? Thank you in advance:)
