Ok, so I've never been as confused as I am right now, so I really hope that someone can help me. I've recently installed a certificate on my website as well as installed the SSL plugins on Wordpress, however some of my pages are still not entirely secure. The error message says: "Mixed Content: The page at 'https://website.dk/en/' was loaded over HTTPS, but requested an insecure image 'http://website.dk/wp-content/uploads/2018/8/bg02.png'. This content should also be served over HTTPS"
So, the problem here is that when I go look for that image in that directory under file manager, it's not there. I'm sure it has been there before, but I probably deleted it. My guess is that this issue occurs because something is still linking to that file. Where and how do I fix this?
NB! website.dk is not the website that I own. Due to restrictions from my employer, I'm not allowed to link anyone to our website at this very moment.
