Those are warning messages.

[Derokorian]

And as suggested by those messages you have output on line 1 of index.php but on line 423 of session.php you are trying to start a session, however (as stated by the message) php cannot send the cookie for the session because of the output on line 1 on index.php (and other output created between line 1 of index and line 423 of session)

The error messages are telling you exactly where the problem is:

output started at /home/eitlabs1/public_html/salmanoreen.com/administrator/index.php:2

You can't have any output before you try to modify the HTTP headers.

When posting PHP code, please use the board's [noparse]

..

[/noparse] bbcode tags as they make your code much easier to read and analyze.

As for your problem.. the error is most certain that first line. Look at what the beginning of your script looks like:

error_reporting(0)
<?php

You've got 'error_reporting(0)' before the first opening <?php tag, so it's being sent as output. Again, you can't have any output before you attempt to modify HTTP headers (since the output will cause them to be sent before you get the chance to modify them).

Furthermore, that's almost a valid PHP statement... but it's got a few problems:

1. You should never set error_reporting to 0 - that would prevent PHP from trying to help you fix your errors. Instead, error_reporting should be set to E_ALL or better.

2. You're missing an ending semicolon.

3. PHP code only gets executed if it's inside of <?php ... ?> tags, and that statement is not inside any such tags.

What is the "new error" that you get?

I'd say the best thing to do would be to clear out the whole site and restore it from backups.

[salmanoreen]

Yes it would be great idea, but unfortunately I have 50,000 files on my hosting and I haven't latest backup 🙁

but at least I have cleaned my one website and now it is working perfectly.

Thanks for your kind help,
