Yeah, I think I’m having a very similar issue! ??
I view a Product’s details; then look at the “Price and Stock Control” options; then click the tick box next to “I have a limited number of this item in stock etc”; then enter “5” items and click the “Update Product” button down the bottom of the page.
I went to the frontend of the website where the Product is in the Products Page. Then entered “5” into the “Quantity” field (assuming you have this option enabled in settings) and click the “Add to Cart” button.
Sure, fine, that seemed to work… now, I went to the Checkout and clicked the “Remove” button to REMOVE the 5 items from the shopping cart. All appears to be fine, right… I don’t think so!
I went back to the Product in the Products Page and tried to repeat the process above… Didn’t work for me! Even entering “1” in the Quantity field didn’t work! It appears I’m “out of stock” on that product now, even though when I go back into WordPress to see the product’s details – it still says there’s 5 items in stock!!
FYI, I’m using WP 2.8.5 and version 3.7.5 of the wp-e-commerce plugin. I hope someone can help us; much appreciated; thank you in advance.
