function getCode - error

Hi. After transferring to another hosting. When booking an error pops up on the library function
public function getCode($srcString)
{
return hash('crc32', (string) $srcString.uniqid());
}
On the server PHP5.3 Joomla 3.4.1
Tell me how to fix or enable a module. Thank you.

Hi,

Solidres use PHP's crc32 hash, you should contact your hosting provider to see if they support it?

Or you can change to another hash function by yourself.

Cheers,
