Why did all my website code suddenly stop working?

[kindredpeople]

Hi there,

Been creating my website the last few months which was going well. Then logged in they other day and the code was no longer active when I previewed the website. For example I under added code to centre pictures, to change the weight and size of font of my headings but it’s back to the original styles.

Could someone help?

The code as was working fine for 4 weeks now it just stopped.

Thanks,

Georgia

Hello Kindredpeople

Hope you are doing well.

Maybe can you check all your themes? I think your theme changed. So, I’ll attach the image and you can check your all theme preview. Maybe you get the right theme.
