I have the same problem with 1.5.5 and raindrop theme, cant get it to work. Anyone who has a clue?

it's because of internal server error:

 

 

turn on error reporting and check error logs (php error log)

you will see what exactly doesnt work

 

for now it is hard to say whats going on without logs.

I dont know if its the same message as DTL will get on his error reporting, but my problem is the same so, the error i get is "Strict Standards: Declaration of Link::getModuleLink() should be compatible with LinkCore::getModuleLink($module, $controller = 'default', array $params = Array, $ssl = false, $id_lang = NULL, $id_shop = NULL) in /var/www/klockkungarna.se/override/classes/Link.php on line 24" on the page, in the backend on loggs it says "The parameter id_lang in function displayDate (Line 211) is deprecated and will be removed in the next major version." dont know if the errors are related. Any ide?

					else if (in_array($attribute_name, array('price', 'weight')))
						$selected_filters[$attribute_name] = array($url_parameters[0], $url_parameters[1]);
					else
					{
						foreach ($url_parameters as $url_parameter)
						{
							$data = Db::getInstance()->getValue('SELECT data FROM `'._DB_PREFIX_.'layered_friendly_url` WHERE `url_key` = \''.md5('/'.$attribute_name.'-'.$url_parameter).'\'');
							if ($data)
								foreach (self::unSerialize($data) as $key_params => $params)
								{
									if (!isset($selected_filters[$key_params]))
										$selected_filters[$key_params] = array();
									foreach ($params as $key_param => $param)
									{
										if (!isset($selected_filters[$key_params][$key_param]))
											$selected_filters[$key_params][$key_param] = array();
										$selected_filters[$key_params][$key_param] = $param;
