To fix the deprecated warning causing by PHP 5.3, all you have to do is replace the

[php]set_magic_quotes_runtime(0); [/php]

with

[php]

//set_magic_quotes_runtime(0);
if(version_compare(PHP_VERSION, ‘5.3.0’, ‘<‘))
{
set_magic_quotes_runtime(0); //18th line
}

[/php]

I have seen this error in wordpress and vbulletin.
