Hi Gepetto007,

Please leave your forum URL and describe more in detail (using some screenshots) what you need to change.

Hi Gepetto007, 

Please use the following CSS code, put it in your current active theme style.css ( Dashboard > Appearance > Editor > Stylesheet).

.colors-custom button{
   background-color: #fff !important;
}

.colors-custom:hover{
   background-color: #fff !important;
}

Delete all caches and check again. 

Thanks Sofy,

I did the way you told me, with no result as you maybe can see, since you're logged on now.

That black is somewhat green, but i did not find it in the theme colors.

Hi again,

I have put the css code in the wrong place. It's now at the end of the file, and it works fine.

Many thanks for your help!

Have a nice day

@gepetto007,

I see another CSS issue on your website. To solve it use this CSS code. Put it in Dashboard > Forums > Settings > Styles > "Custom CSS Code" textarea:

#wpforo #wpforo-wrap .wpf-button{
background: #649E2D !important
}
