You may need to check your setting under Configuration/Stock
In there you have an option to allow checkout with low and out of stock items, this may need to be set to true.

Remember to ALWAYS test mods out on a local test server before putting them onto an active store, all too often mods will conflict with other mods you have installed. Because of the large number of mods available we seldom know of a problem until someone runs into it.
Thank you for reply sir.

I checked the mod version is 1.4.14, Allow checkout is set as TRUE in Configuration/Stock. Do I still miss something?

Thanks...
