[SOLVED] Big problems in Chrome and IE - empty cart, user can't login

[micho88]

I am using Prestashop 1.5.4.1 , using SSL on my site - http://www.112pc.si and I am almost finalizing setup all modules, translations, design and other stuff, so I will start adding and selling real products..
 
Yesterday and today I was working on removing taxes(BO and files), css, design, content, translations(BO and files), editing Bankwire details, install "Order reference change mod", remove express checkout button of PayPal, changing some images, configure PayPal module(not worked; uninstall, install and configure again), changed position and look of payment modules in last step of cart and probably other things (I am not well organised and usually working more things at the same time).

 

So today once after configured PayPal module I noticed that I can't login in front office(using Chrome). I opened Firefox, where I was logged in before, so I tried to logout, but with no success. Both things page was just loaded normally, but then, like I wouldn't click anything. I enable logging and got no errors. Tried IE, same thing. I started googling and trying to resolve problem. Everything I try; I made change, go to my site, test, if no success change to original. I tried disable FriendlyURLs, disable SSL, disable mobile theme, try to change theme to default, in /themes/default/authentication.tpl (about line 97 there was line:

url: baseUri,

change it to:

url: baseUri + 'index.php?controller=authentication', ) - not helped, try to change domain links in BO

 

While I was trying to figure out problem I notice, that if I try to make new user I got Technical Error:

unable to load form

Details:
Error thrown: [object Object]

Text status: Parsererror

 

 

I found one advice: The content area must be inside the div with id "center_column"!!!

But not really understand, what did he/she mean and where can I check that.

 

 

Suddenly I see that in Firefox works perfectly again. In Chrome and IE can't login and when I add something to cart, cart is still empty.

 

 

 

That I can tell for now. Please help me! I really don't want to start again with fresh installation, because I am working soo long on this.

 

Thanks for every answer
