color customizer not working

I tried making changes on color customizer and it does not work. Ever since that warning came up it has been a problem. I tried resetting everything because it worked once before but it didn’t this time it just created a bunch more work for me. I have to say wordpress is a real pain, always seems like when you get things done it throws new problems at you. i am starting to appreciate rapidweaver a lot more. No disrespect but i never had these kind of issues with rapidweaver in the two years i used it.
