Font issues on site

Hi there,

Since the recent updates to GP over the last 2-3 months, all my text and headings are now defaulting to white, instead of black. It normally would default to black, so now I can’t see what I’m typing (white text on a white screen). I did try to fix this in the customizer but it’s not working for some reason. I’m not an expert when it comes to this stuff unfortunately…

Also, the margin font padding is not working when I use “auto” to centre the container / text / content. I’ve also tried the align centre button but it’s not working. It often just sits on the left hand side of the page.

Is there something I need to change on my WP backend? I updated the GP plugin and cleared my cache.

Thanks for your help!
