----->sess_save_path : BASEPATH.'projet/cache'
----->uri_protocol : REQUEST_URI 
----->index_page : 'index.php'

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

    }

Thank you very much

1) Make sure when you save your files in your editor that they are not saved with the BOM encoding mark!

SEE: The byte-order mark (BOM) in HTML

2) Make sure you do not have any white space before the opening php tag.

3) Your online server may be case sensitive and require all lower case filenames.

What did you Try? What did you Get? What did you Expect?

thanks for your anwser

while i save my files i think that i 've done forever without the BOM,and all my opening php tag doesn't contain space before and it may be true about the case  sensitive and requires all lower case filenames

but now ,my project doesn't work ,i see many tutorial but it s not htacess,session,or configuration;but i don't know what,it's not too the database because when i change the function in the routes.php,it show me aparts of data in database

make sure that your base_url has an ending / slash on it.

Also make sure that your index.php file has the application and system paths set correctly.
