Hi,
So, TobiasBg was right. I was change it back, with new fix:
$tablepress_tables = TablePress::$controller->model_table->load_all();
foreach( $tablepress_tables as $table_id ) {
$table = TablePress::$controller->model_table->load( $table_id );
// $table is now the table array, with ID, name, and description
}
