[BUG] Personnalized color selection in Wordpress template isn't working

[mangasmaster]

Hi,

I try to choose the Greenlet template for my website template. However, everytime I try to change a color, whether by clicking on the grid of changing the Hex code, the color refuses to change and stays in its primary color. Is it possible to fix this? The website I want to build has a specific color palette.

Thank you and have a nice day.
