Hi there, I need to add a custom field code to the template of the TT portfolio grid in order to show it before the portfolio title on the hover.

I tried to edit /inc/portfolio-loadmore.php (line 127) and put it in my child theme creating the inc/ folder and duplicating the php file there but the change is not been shown. 

this is where I need the custom field to appear.

Can you point me if I’m editing the correct file or if I need to do anything else.

Thanks in advance.
