Error after install - Site down - Please Help

Hi there,
Installed Shapely theme and everything went smooth (no errors). When I tried to go to the settings page of the site I got the error below. When opening any site page I get the same error below:

Parse error: syntax error, unexpected ‘[’ in /home/orkest5/public_html/moonwear.cl/wp-content/themes/shapely/inc/widgets/widget-home-clients.php on line 65

I’ve got FTP access to the site. Could yoi please please help fix this?
Thanks so much,
Sergio
www.moonwear.cl

Adding more details:
I’ve already tried replacing [”] to simply ” a stated in another post, no luck.
I could revert to the storefront theme (is installed) if you show me how as I can’t even logon to the site to do it (get same error).
I know I don’t have the latest PHP version, fear the host provider will take ages to upgrade so this wouldn’t be an option to get this fixed for now.
Any hints you can provide to restore the site?
Thanks so much,
Sergio

Adding more info:
https://wordpress.org/support/topic/theme-not-working-how-to-swap-default-theme-using-ftp, last post worked for me to revert to the default site. Now, I’d still like to install the Shapely theme… What are my options?
Thanks!
Sergio

Hi Sergio,

I hope you are well today and thanks for posting here.

Yes you are right it happens due to older version of PHP.

Could you please try using latest version of theme by downloading it from this page https://github.com/puikinsh/Shapely ?

Best Regards,
