I made some minor adjustments in the CSS of the Metropolis template. As well as the K2 CSS. When I upload the new CSS files everything is working fine. But when I enable rokbooster everything is back to normal te next day.
How can I make some changes in the CSS without Rokbooster deleting it again?
If you are using Gantry 4 (or later) you can create a file using a simple text editor for custom css and name it using this format: templatefolder-custom.css (e.g., rt_kirigami-custom.css or gantry-custom.css).
