Strange message in Back Office: Modules

[Aldeag]

Why I get this message when I now access to modules in Back Office?
It only happened to me when I upgraded from 1.3.6 to 1.4.1

Parse error: syntax error, unexpected ';' in /var/www/vhosts/XXXXXX.com/httpdocs/prestashop/classes/Tools.php(1723) : eval()'d code on line 1

Notice: Undefined variable: x in /var/www/vhosts/XXXXXX.com/httpdocs/prestashop/classes/Tools.php on line 1724
