Error on modifier.regex_replace.php on line 35

[Tuussooo]

Hello, i am reviewing my log file and i found these errors:

 

 

[25-Oct-2016 15:08:16 Europe/Madrid] PHP Warning: preg_replace(): Unknown modifier '(' in /tools/smarty/plugins/modifier.regex_replace.php on line 35

[25-Oct-2016 15:08:16 Europe/Madrid] PHP Warning: preg_replace(): Compilation failed: nothing to repeat at offset 0 in /tools/smarty/plugins/modifier.regex_replace.php on line 35

 

Anyone know how to solve it?

 

The line 35 of modifier.regex_replace.php is return preg_replace($search, $replace, $string); so i think that error come from other file

 

I am using prestashop 1.6.1.7

 

Thanks
