Problem with Customizr Theme

I am using Customizr Verision 3.1.6 and made a small change to the php file titled : ‘class-header-header_main.php’ after making this change the site crashing showing this error:

‘Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /data/24/3/137/37/3300526/user/3683555/htdocs/home/wp-content/themes/customizr/parts/class-header-header_main.php on line 299’

This can be viewed at https://038ee0b.netsolhost.com/home/ .

I need to fix this immediately as this site needs to be deployed as soon as possible. I was making a last minute change to change the heading type.

So far I have access through the ftp and deleted the ‘class-header-header_main.php’ file and reinstalled the file from customizr version 3.1.11.
When I deleted the file I was still getting the same error and still have the same error after reinstallation.

Please help as soon as possible.

Thank you
