Fatal error: Call to undefined method SplFileInfo::getExtension()

Hi, I’ve just uploaded a site from my local, to a live development server but I’m getting the following error when accessing the website.

Fatal error: Call to undefined method SplFileInfo::getExtension() in /var/www/vhosts/domain.co.uk/subdomain.domain.co.uk/system/ee/EllisLab/ExpressionEngine/Model/Template/Snippet.php on line 214

ExpressionEngine 3.2.1

Could someone please let me know what I need to do to fix this.

Thanks

Wayne.
