Problem with session on default page

I probably found the source of problem.

In my .htaccess:

Code:

<IfModule mod_rewrite.c>

RewriteEngine On
RewriteBase /

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.***.pl/$1 [R,L]

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#Checks to
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

ErrorDocument 404 /index.php

</IfModule>

I change:

Code:

RewriteRule ^(.*)$ https://www.***.pl/$1 [R,L]

to:

Code:

RewriteRule ^(.*)$ https://***.pl/$1 [R,L]

and I think it's finally fine.

Thank you for help!
