I tell you: One guy installed prestashop and one theme to my friend. But this theme doesn't work correctly. So, I'm helping my friend to restore the default theme.
We try to activate the default theme, but we encounter a lot of problems. There are a lot of modules that don't appears or don't appears correctly. I think that maybe the old guy changed some css.
An example, the top bar menu don't appears. The block of the login is in a strange position.... I revised the modules and are activated and I try to reset them.
So, any indication or help? Thanks !!
