Cannot activate Shapely theme

I am trying to install and activate the theme but every time I activate it, the entire site goes down with blank screen.
If I instal via wordpress I get the following error message
[31-Oct-2017 11:41:56] PHP Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home3/silotcom/public_html/savvy/wp-content/themes/shapely/inc/libraries/epsilon-framework/class-epsilon-framework.php on line 244

If I upload the theme files I get the following error message
[31-Oct-2017 11:47:47] PHP Parse error: syntax error, unexpected T_FUNCTION in /home3/silotcom/public_html/savvy/wp-content/themes/shapely/inc/customizer.php on line 24

Hello there,

I hope you are doing well today.

Please delete the theme then download and install a new version of the theme:
https://colorlib.com/wp/themes/shapely/

Also, contact your hosting provider and have them ensure you are using either PHP version 5.6 or higher.

Best Regards,
