Module Error on Save when Deployed

brandonkboswell

I have two modules that I have created that work together: Products & Categories. They work wonderfully when developing locally, but when I deployed them to my Network Solutions hosting I now get "internal error or misconfiguration" errors. All other pages on the site work fine except for the modules. I'm pretty clueless as to what is causing this, any ideas. Screenshot Below:


--categories_model.php
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

require_once(FUEL_PATH.'models/base_module_model.php');

class Categories_model extends Base_module_model {

public $record_class = 'Category';

function __construct()
{
parent::__construct('categories');
}


// cleanup category to products
function on_after_delete($where)
{
$this->delete_related('categories_to_products_model', 'category_id', $where);
}

// add unique name validation
function on_before_validate($values)
{
if (!empty($values['id']))
{
$this->add_validation('name', array(&$this, 'is_editable'), lang('error_val_empty_or_already_exists', lang('form_label_name')), array('name', $values['id']));
}
else
{
$this->add_validation('name', array(&$this, 'is_new'), lang('error_val_empty_or_already_exists', lang('form_label_name')), 'name');
}
return $values;
}

function does_category_match($category) {
$categories = $this->find_all();

foreach($categories as $cat){
if ($cat->name == $category)
{
return true;
}
}
//If none returned true, then return false
return false;
}

}

class Category_model extends Base_module_record {

function get_products()

Thank you for your help,

Do you get this error only when you save something or do you get it as soon as you click on the products module?

I do sometimes get this error when just opening the products module, but this does not occur every time.

admin

The list area is AJAXed in which is why you see the error displayed in that way (as opposed to the whole page). We've had problems with Network Solutions in the past, regarding .htaccess, but don't remember anything quite like what you have. Regardless, I would look at your htaccess file. Here is an article I found regarding a similar situation:

Hosting on Network Solutions has been a nightmare, I'll see if I can get my client to switch. I haven't had any of these issues on other hosting providers I've tried.
