I'm working on this zen cart site. A Love Supreme Shop In new and featured listings only the first letter of the product description appears whether I use a custom template or the default. I'm using 1.3.9 but the data has come from a 1.3.0 site.
When product descriptions are shown on all products they show up fine. Is the description being put into an array incorrectly and only the first element of the array being displayed?
Go to admin->configuration->new listing, and look at the value of Display Product Description. I wonder if yours is 0. It should be 120 or 150. If you don't see this setting, your database is missing values.
Failing that look at the file
includes/templates/YOUR_TEMPLATE/templates/tpl_modules_products_new_listing.php
and see how description is being handled.
