[n1crack]

removed dependency of symfony, can you update the library and test it ?

Seems something that related to :

You can try saving the files without BOM (remove bom)

I recreated the files on my namecheap shared hosting (php 5.6) via cpanel and copy pasted my code.
I am getting different error this time

Parse error: syntax error, unexpected ':', expecting ';' or '{' in /home/crafctuz/ossamarafique.com/datatable/vendor/ozdemir/datatables/src/Datatables.php on line 68

After changing php version to 7.3 error is changed
Fatal error: Uncaught PDOException: could not find driver in /home/crafctuz/ossamarafique.com/datatable/vendor/ozdemir/datatables/src/DB/MySQL.php:45 Stack trace: #0 /home/crafctuz/ossamarafique.com/datatable/vendor/ozdemir/datatables/src/DB/MySQL.php(45): PDO->__construct('mysql:host=loca...', 'crafctuz_test', 'crafctuz_test') #1 /home/crafctuz/ossamarafique.com/datatable/vendor/ozdemir/datatables/src/Datatables.php(59): Ozdemir\Datatables\DB\MySQL->connect() #2 /home/crafctuz/ossamarafique.com/datatable/ajax.php(29): Ozdemir\Datatables\Datatables->__construct(Object(Ozdemir\Datatables\DB\MySQL)) #3 {main} thrown in /home/crafctuz/ossamarafique.com/datatable/vendor/ozdemir/datatables/src/DB/MySQL.php on line 45

Now after changing PHP version to 7.1 Errors are gone but the same problem again

{"draw":0,"recordsTotal":2,"recordsFiltered":2,"data":[["1","admin"],["2","user"]]}HTTP/1.0 200 OK
Cache-Control: no-cache, private
Content-Type:  application/json
Date:          Fri, 11 Jan 2019 15:16:40 GMT

{"draw":0,"recordsTotal":2,"recordsFiltered":2,"data":[["1","admin"],["2","user"]]}

Now, PHP version is 7.3 and I enabled pdo_mysql.
Problem is same, it is showing the headers.

This problem looks similar to

Couldn't reproduce the error. Sorry.

Can you try

echo json_encode( $dt->generate()->toArray() );

[n1crack]

I think this is something related to webserver settings
Can you check nginx setup or .htaccess file if you are using apache.

[OssamaRafique]

I already used above thing, But the default method was not working that's why I opened the issue.
My .htaccess code ::

#turn on url rewriting 
RewriteEngine on
#remove the need for .php extention 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}\.php -f 
RewriteRule ^(.*)$ $1.php
ErrorDocument 404 /404-error.php
ErrorDocument 403 /assets/pages/403.php

But it has nothing to do with that header output.

[OssamaRafique]

This error is showing on my both local server and NameCheap shared hosting.

Its working now, Thank you! 👍
