My layout has broken down completely!

I’ve set up WP and it worked perfectly, made quite a lot of changes in the layout and installed e-commerce. Worked on it for 4 days.

Then I moved the directory from mydomain/blogg/main to mydomain/.

I shouldn’t have done that it seems… The layout, including the admin pages, i nulled!!

I’ve moved the directorys and files back to their original place but it still looks like this: https://www.vintagemaniac.net/blogg/main/

please, please help me!
