Showing the product title
Long product titles are set to truncate by default to even out the layout of the product grid.
Below is an example of what the Product title looks like when it's truncated (image on the left) compared to when the full title is showing (image on the right).
How to Show the Full Product Title
Go to your Shopify Admin, and select Online Store.
Select your Debutify Shopify theme and click on Customize.
Click on Theme settings.
Click on Advanced settings.
Under the Product grid, untick the Truncate product title box.
The product title should be shown in full.
