Hello,

I have turned to light this setting http://prntscr.com/iuvhan and got this result http://prntscr.com/iuvgni

Then I changed color to http://prntscr.com/iuvhso just to test and got this result http://prntscr.com/iuvidf

Finally, I made it transparent http://prntscr.com/iuvj4p and got this result http://prntscr.com/iuvje8 You can also disable page title in page setting

What background do you want in your page title? Now page title settings are the same as before.

Best Regards
