Post page problems

I was just due to launch a site. I have used a Child Theme to make my changes. I notices that Customizr had issued an update so opted to update. This immediately broken my site so I reverted back to a back-up. Everything now works, and the posts show except I am getting the following message appearing on the bottom of the page my posts link to:

Warning: in_array() expects parameter 2 to be array, null given in /var/sites/p/plan-2-build.co.uk/public_html/wp-content/themes/customizr/parts/class-content-post_list.php on line 100

I have tried to use other back-ups but nothing works. The line in questions is:

if( in_array( get_post_format(), tc__f(‘post_type_with_no_headers’) ) )

Any help would be great thanks.
