Parse error: syntax error, unexpected T_FUNCTION

I just installed the Shapely theme and uploaded the demo content and widget content but when I try to load the prview or activate the theme, I receive the following error:

Parse error: syntax error, unexpected T_FUNCTION in /home/content/19/9046919/html/thisisjace/wp-content/themes/shapely/inc/customizer.php on line 24

Hello there,

I hope you are doing well today.

Please try to disable any third party plugins that you may have active because one of the plugins ma be causing a conflict here.

Best Regards,
Support

Hi,

Which PHP version you’re using? if you’re in doubt contact your hosting provider. Make sure it is at least 5.4+. Check WordPress requirements, Requirements | WordPress.org and make sure you met the requirements.

Let us know,

Thanks,
