I created a copy of ShowCase Template and renamed the template accordingly. I then created my page using the template.
However, I noted the Format of the Page goes all wrong, it spreads right across the page.
If I set the template of the page to be the standard ShowCase it works 100%.
I have not changed ANY code in the Showcase.php template.
Even if I coyp the showcase.php to my child theme without any code changes it still throws the layout off.
Please can anybody advise
