Derivado [ERRO] Erro na database do xampp.

[Gabriel Alves 0]

Boa noite,

Estou fazendo o site de meu servidor, ele fica online e tudo mais, ai logo como administrador para editar o site e aparece os seguintes erros:

 

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\classes\databaselist.php on line 30

Fatal error: Call to a member function fetchAll() on a non-object in C:\xampp\htdocs\classes\databaselist.php on line 68

 

Estarei postando as linhas que possuem o erro abaixo em Spoiler:

Linha 30:

  Mostrar conteúdo oculto

foreach($this->fields as $fieldName)

 

Linha 68:

  Mostrar conteúdo oculto

$this->data = $this->getDatabaseHandler()->query($query)->fetchAll();

 

Chave do codigo onde esta situado as duas linhas

  Mostrar conteúdo oculto

{

$fieldsArray = array();

 

if(count($this->fields) > 0)

foreach($this->fields as $fieldName)

$fieldsArray[$fieldName] = $this->getDatabaseHandler()->tableName($this->table) . '.' . $this->getDatabaseHandler()->fieldName($fieldName);

 

if(count($this->extraFields) > 0)

foreach($this->extraFields as $field)

if(!$field->hasAlias())

$fieldsArray[] = $this->getDatabaseHandler()->tableName($field->getTable()) . '.' . $this->getDatabaseHandler()->fieldName($field->getName());
