An error has occurred using module front page plus that did not in the past.

The system info is as follows:
PHP Built On:    Linux
Database Version:    mysql 5.5.32-log (Version: 5.5.32)
PHP Version:    5.3.3
Web Server:    Apache
Web Server to PHP interface:    cgi-fcgi
Version    Elxis 2009.3 Stable rev2691 [ Aphrodite ] 14-July-2012 09:48 GMT+2

I am not sure if this has to do with the version of php or something else.

The problem is on this site http://www.129dimotiko.mysch.gr/

You have too much content in some article's introduction text and function preg_replace reaches a hard limit. Let just a paragraph in intro text and put rest text in main text editor.
