Help to find error on page - does not load correct.
http://butiknille.dk has suddenly have some errors. Some external developers have made som changes (header, footer and some SEO) but they say that their work is not the root of the errors.
When I load the page on mobile it is like it only uses 3/4 of the page. I have deactivated the responsive design, and then there are some empty areas in the header. Further more the frontpage does not load some static blocks and therefore I have pasted the code directly in the home CMS.
In FF i get one header without text and another in Safari.
Does anyone have an idea of how to find root cause?
