lots of scrambled text at the top of each page

I have just set up a localhost and it was working fine until I started to enable some contrib modules. I now get this:
'weight']) { return strcasecmp($a['name'], $b['name']); } return ($a['weight'] < $b['weight']) ? -1 : 1; } /** * Sort each level of a component tree by weight and name */ function _webform_components_tree_sort($tree) { if (is_array($tree['children'])) { uasort($tree['children'], "_webform_components_sort"); foreach ($tree['children'] as $cid => $component) { $return[$cid] = _webform_components_tree_sort($component); } $tree['children'] = $return; } return $tree; } function _webform_load_components($return_all = FALSE, $reset = FALSE) { static $component_list, $enabled_list; if (!isset($component_list) || $reset) { $component_list = array(); $enabled_list = array(); $path = drupal_get_path('module', 'webform')."/components"; $files = file_scan_directory($path, '^.*\.inc$'); foreach ($files as $filename => $file) { $enabled = variable_get('webform_enable_'.$file->name, 1); if ($return_all || $enabled) { include_once($filename); $component_list[$file->name] = t($file->name); } if ($enabled) { $enabled_list[$file->name] = t($file->name); } } } // Ensure only wanted components are returned, even all are loaded. return $return_all ? $component_list : array_intersect_assoc($component_list, $enabled_list); }

at the top of EACH page on the site.

Please help
