Hi tim92109!
Most major eCommerce platforms do suggest some measure to copy the core theme templates into your active theme directory. I know EDD, WPeC and Woo all do this. If you made changes to the the core theme files inside the plugin, those would of course be overwritten on an upgrade. If you copied them to your active theme directory, those would not be overwritten on upgrade.
Hope that helps!
It’s actually working now. It was only copying the template page(s) to the theme directory and not using them. For some reason it’s not using them. I mostly wasn’t happy because of the use of tables (had to replace with divs so I could customize), the incompatibility with the WordPress upgrade (to 4.0), and some little things.
Your quick reply does show that you care though… and that’s somewhat of an asset and rarity when it comes to WP plugin developers.
It’s just an opinion, but something I noticed with extensions is that people appreciate your work more if you offer it full-featured for free download and charge $ for cool plugins. And you can create tons for an e-commerce… 1 page checkout, plugin themes, other major extensions’ integrations, less common payment plugins (most come with paypal), import/export, and the list goes on forever.
WordPress isn’t my preferred platform for e-commerce and I really haven’t used enough other WP e-commerce extensions to say that there’s a better solution. I think I was a little harsh on my review so I’ll go ahead and edit it for ya, Justin, and bump it up a star.
Sorry – now you’ll probably want to edit your post because it sounds like you’re answering a different issue than I posted.
