Most of settings dropped to default after moving from localhost

[Itinerant]

I installed presetashop 1.5.3 on my MAMP server to work on front-end, modules and so on. 

I used one of the Leo Themes for my project, and it included some new modules.
 

Anyways, i did a lot of customising: edited css for modules, edited code sometimes, modules' settings, products, content....
 

And when i moved my site to another server (i moved files via FTP, made a db backup and deployed it on a sever and did all the nessecary stuff), huge part of these changes just gone and my site turned into a mess.

 

Here are some things i changed on my local server which are gone on hosting server:
 

- Products. There had been some sample products with the theme i use, but now i see just default presetashop products (ipod, earphones etc).

- Modules on/off. Seems like all the modules installed are now on, even those i turned off on local server.

- Module's content. Footer links, promotional text modules - all that stuff now has default content. 

Please, help to solve this problem. 

Is there any way to recover my site? I still got my localhost prestashop instance and it works fine.

 

I attached printscreens for you to understand how scary my problem is)

1) please turn on error reporting, you will see then potential errors in parsing (maybe your host use different php with different settings)

2) what you've got in browser console error log?
