Joomla Love Factory legacy.php getInstance

Question

I have a Love Factory extension in Joomla.

Love Factory 4.1.1

Joomla version 3.1

I extended interaction so the user can become a fan. But when the JModelLegacy::getInstance (html.php) tries to get an Instance it crashed on require_once $path in legacy.php.

I tried to change only format in friends model and then it does not load it too.

It just take part of the code from required class and paste it on the screen. Example from friend.php

<?php
//class definition missing
//function definition missing

  $result = $table->load(array('sender_id' => $userId, 'receiver_id' => $user->id, 'pending' => 1));

  if (!$result) {

Is there any special way how the file must be written? Or did anyone else had the same problem?

Answer 1

The problem was caused by the line endings. NetBeans changed the line endings and then the server was not able with function require_once load the content correctly.

Solution was download a plugin to NetBeans that allows to change line endings.
