Hi
On Dark theme 404 page – there is something amiss with the coding on the page. See image attached. It basically shows a background image but the image it links to is a screenshot of functions – here –>> https://xstore.8theme.com/demos/dark/wp-content/themes/xstore/images/404-dark.png
Image is here -> https://i.imgur.com/sJAxa8z.png
As you can see, I have highlighted the relevant block however the page is blank but it is still an issue.
The theme etc is here -> https://xstore.8theme.com/demos/dark/404
Thanks
