Add this to your htaccess file

php_value output_buffering on


I add what you suggest, but it still not working.


Login.php line 83 can you paste it here?


Hi @rjayswal78!

Then try php_flag output_buffering on instead.


Thank you for your support I found my mistake and correct it.
Now its working.

My mistake is i use “echo” in controller to print statement.
I just remove it.
