Does not work

I’ve now found this useful plugin. At first glance, he knows everything I need. That’s exactly what I was looking for.

But unfortunately..

When I make changes to css, no changes will be made after the changes have been made. Viewing the source code in the browser does not make any changes, no results. It’s like I did not do anything.

However, if I delete the contents of the whole css, then there is a change.

I tried this with many templates, and each of them has this problem. I tried the settings, I did not succeed.

Since I did not find a similar person who has this problem, I suspect that I am lame to this. 😀

Can you help me?
