I can show you the code of all the pages you want.
I've disabled the other plugins and change the theme but the problem is still here.
I think it's a problem with my server because I've another background logo plugin that doesn't want to be appear in the admin dashboard
The website is actually on a private secure network so you cannot access it :(
Thank you in advance,
