Saved Changes Not Taking Effect

Hi, we have two sites with WordPress, both based on the Enfold theme. They are meant to be sister sites so other than content and layout, their color schemes have to be identical. But, one site is accepting my changes and the other is not. It keeps saying “Alright, sparky – changes saved” etc. but the changes aren’t actually taking place. If you return to the Enfold>Styling options menu, it shows the colors set to what I want, but the actual published page is not showing these changes. The other site, however – is working fine. Could it be a bug, perhaps?

Thanks,

Lea
