include() working on localhost but not on live website

Question

I have a situation where a php line is working in localhost, but not on live website. The line of code is below:

include( get_template_directory().'/mpdf-master/mpdf.php');

I am using

• WordPress 4.6.1
• Contact form 7 Plugin - version 4.5
• mPDF library to create PDF
• Php version in localhost:- 5.6 and in live webserver:- 5.5

What would be the reason behind such behavior?

EDIT: On inspecting i found an ajax error

JSON.parse: unexpected character at line 2 column 1 of the JSON data

Does this helps to resolve issue?

Does this happens due to directory permission 755?

Answer 1

use include (TEMPLATEPATH . '/mpdf-master/mpdf.php'); instead.

if you are trying to call the file in functions.php use the below one than.

require_once( TEMPLATEPATH."/mpdf-master/mpdf.php" );

if there is a wrong path it must tell you in the browser or just enable the debug to understand whats wrong

If still not working the problem can be a js conflict between contact form 7 and mpdf

Answer 2

try like

include( dirname(__FILE__).'/mpdf-master/mpdf.php');
