Having some issues with a clean install of 1.3.9h using the original database.
Some info: Originally installed 1.2.7 and have upgraded with success up to 1.3.8a.
Created a new file and installed 1.3.9h connecting to the original db as before, and the only thing having a problem is the stock level calculations.
NO WARNING MESSAGE at check out. Customer can put more in cart than allowed; however, Bumps customer back to shopping cart page with no explaination when checkout button clicked.
Also, installed Stock by attributes and that does put up a warning but does not calculate the remaining stock per attribute. Also bumps customer back, with warning.
