[1.4.4.1] Problem with product editing in BO

[Irminsul]

Hello

 

I've got the following problem - when I try to save product, after editing in back office, page reloads very long, and then throws an error:

 

Fatal error: Maximum execution time of 30 seconds exceeded in /home/tysiacmebli/public_html/classes/Search.php on line 103

 

Code inside classes/Search.php looks like this (line 103 is $string = preg_replace('/['.PREG_CLASS_SEARCH_EXCLUDE.']+/u', ' ', $string); ):

 

class SearchCore
{
public static function sanitize($string, $id_lang, $indexation = false)
{
 $string = Tools::strtolower(strip_tags($string));
 $string = html_entity_decode($string, ENT_NOQUOTES, 'utf-8');
 $string = preg_replace('/(['.PREG_CLASS_NUMBERS.']+)['.PREG_CLASS_PUNCTUATION.']+(?=['.PREG_CLASS_NUMBERS.'])/u', '\1', $string);
 $string = preg_replace('/['.PREG_CLASS_SEARCH_EXCLUDE.']+/u', ' ', $string);
 if ($indexation)
  $string = preg_replace('/[._-]+/', '', $string);
 else
 {
  $string = preg_replace('/[._]+/', '', $string);
  $string = ltrim(preg_replace('/([^ ])-/', '$1', ' '.$string));
  $string = preg_replace('/[._]+/', '', $string);
  $string = preg_replace('/[^\s]-+/', '', $string);
 }

 

Could it be a server issue? Or maybe something with database? On localhost I've got 7 products, and I can save without problem. On the real website there are about 4300 products.
