Can't change my wallpaper (Manjaro Awesome)

Hey guys, I have installed manjaro awesome recently and everything works fine so far but whenever I try to change my desktop wallpaper nothing happens, it simply keeps the same one that already comes pre installed with it , I tried different kernel versions and checked the settings under xfc4-desktop and the full path to the wallpaper that I want is there, do you have any idea what may be causing this issue ? thanks !

The wallpaper is likely set in a config file somewhere, as Awesome WM does not use xfce settings as far as I know.
