Migrate from localhost to remote problem

hi there, i ve a big problem with the migration of my wordpress blog from localhost (where it works perfectly) to the internet.

If i write it’s because i really spent lot of times for the solution, but i didn’t find anything useful. I read all the guides and tutorials but nothing.

I succesfully migrate the website. But the are really a lot of elements who doesn’t work at all. My homepage is different, there is no header image, no sidebar either with all her widgets! the pages are really messed up, layout too…the homepage had a loop with lots of posts, but you can see only one…i don’t know what i m doing wrong. You can see the site here : https://www.lidia.me

What i did:
0) I went to localhost folder wamp/www/joedoeblog/blog/
1) (Localhost) open PhpmyAdmin and exported the same database of the localhost in a .sql format
2) edited with notepad+++ this file and change every reference to the localhost with the website url https://www.lidia.me (so for example if i had localhost/joedoeblog/blog/wpcontent…now i have https://www.lidia.me/wpcontent….)
3)loaded the edited database to the phpmyadmin of my hosting service.
4) loaded the wordpress folder of the localhost in the /public_html folder of my hosting web server (as it mentioned to do that), thanks to Filezilla.
5) changed wp_config with the exact name of database.

don’t know why i have a bad visualization of the content; the content exists, but it seems like the order of the page is messed up..the only page which seems (at least a little) to work is the ABOUT page..everything is in the exact same directory as always.

thanks for your patience!
