Thank you for the response!
The first part:
Please go to the page’s General Settings > Page Options & Style > Header Color Style for Header 1, make sure to have selected the dark version.
…is done. That was simple enough to find and seems to have fixed my issue on it’s own.
I also completed this recommendation:
After this go to Codeless Slider > Codeless Slider Options > Layout, check the “Menu & Slider Navigation Color” option to be the same as the one chosen in page’s options. Do this for every slide of the slider you are using.
Thank you again!
Was able to figure this out myself, sorry.
Solution was in Specular > Options > Header Options > Make Transparency: “Off”
