pcre.backtrack_limit

Hello,
From the last two days, the site in the front of the site is displayed with an error. PHP regular expression limit reached (pcre.backtrack_limit)
The site administration section works well, and this problem is only in the front-end.
When the site template is changed, the site will display without errors, but when I select the hi-fi template, the error will be displayed again.
The site address is : ipicompany.ir
Thanks,

I found this in your link:
just add after }:
ini_set('pcre.backtrack_limit', 150000);
to your configuration.php file.

I add this line end of my configuration.php
public $ini_set('pcre.backtrack_limit', 150000);
and test this one too:
ini_set('pcre.backtrack_limit', 150000);

Not work...

Any Idea??

No sorry!
