All of a sudden, yesterday, my site shopping cart won't checkout. My customers called complaining about being unable to checkout. When you proceed to checkout it links back to home. Last night it worked for a second but changed what was in the shopping cart to another product and price. Today, it is back to linking to home and doing nothing.! Help, this is my only full-time income!!
