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:
Responsive->css->Styles.css.
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?
Ty.
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.
