Changes Made on Theme Don’t Show Up Online

Hi,

I’ve been created a static page for my blog + made custom changes on the general look for the posts. Everything has been saved several times. The static page is selected + nothing is selected on the posts section. And I have specified that I want the colors to be picked from the color customizer in the Highend options, yet nothing appears as supposed to online.

I’ve tried everything I can think of and would really appreciate any help with this.
Thank you in advance,

Nathalie
