Not sure if this is WPEC-specific or a general WP issue, but...
I have a product category "Create Your Shirt". I also have a page with the same name, which I link to on the home page using the page's permalink. I added this page to the menu, changing the title to "Create Your Own." The page has a shortcode to display products in the category "Create Your Shirt".
All was well for a few weeks, but we just noticed that the "Create Your Shirt" page's permalink changed from "create-your-shirt" to "create-your-shirt-2", which broke the link on the home page.
I was able to change the permalink back (don't forget to Update the page or the change won't stick), but I'm wondering what might have caused the system changed the permalink? Thanks for any info!!
