Styles.less Can't Be Loaded

So, while Rebuild cache automatically was set to off, I did some style changes, and could not understand, why are they not showing up.

I tried to change theme folder that was main theme, called Bright_Theme, and then:

So, when I turned Rebuild cache automatically on, all my website was without any css. Plain html.

I tried to delete all of my changes, but it looks like it doesn't work, and I have no backup.

Question, how should I fix the problem now?


P.S I tried to find, how to download original Bright Theme css/less but could not find any, in cs-cart website.

Ok, I fixed it by downloading demo version, and replacing Less data from original theme.
