I've got the corecommerce module running on a site on 5.4.0 using the Paypal gateway. Its accepting the payments but the orders aren't going through to the orders area of the site & the order email isn't being sent to the admin.

I have the blog, corecommerce, defunct social icons, gallery, image slider & table shipping blocks installed. Is there any known issues with these conflicting with each other?

I have about 25 products in the shop at the minute, if I uninstall & then reinstall the shop will I lose all the products?
