if that connection.php is that secret, u dont want to show it

we cant help u,

cause that error message line (at your 1st post), the message stating the connection.php is having error.

if u dont show that, we cant help u

 

if you dont show the file, then we cant help even it is your final second

only god can help u

 

 

here is what i suggest you to do before showing that connection.php

use **** to replace the mysql address, username, password, db name

as people here are trying to tell you, your error message clearly states:

 

output started at C:\xampp\htdocs\widget_corp\includes\connection.php:1)

 

That means that something on line 1 of that file, is producing output. It may be as simple as a space before the <?php or may be something else, but that is where your error is.
