Hi guys I'm trying to add a new page type to my website template which seems pretty straight forward except it doesn't seem to actually create the page and I get this error when applying the page type.

An unexpected error occurred.

File /home/dlkey/public_html/diamondlockandkey/themes/diamond-lockandkeys-theme/default.php not found. All themes need default.php and view.php files in them. Consult concrete5 documentation on how to create these files.

I've searched around but haven't been able to find a definitive answer on how to fix it so if anyone could help that would be great!

Cheers
