Earlier today we released version 1.2.0 of Pro2Store. In this update was a huge change in how we deal with the number input into the system, everything form Base Price, discounts etc.
In the install script, there was code that ran to convert your numbers in the database from floats (for example "34.55") to minor integers (for example 3455). This is a much better way of dealing with numbers in an e-commerce system and we wanted to make the change sooner rather than later.
We tested this script as much as we could but there was some cases were the numbers weren't updating.
We have removed the offending code from the install script in version 1.2.4...
...this means that you will now need to change some of the values in your backend after you update.
We apologise for this inconvenience.
Please ask us on the forum is you need any assistance, we'd be glad to help.
Many thanks for you patience.
In related news, we have now extended our testing team for the next releases to prevent anything like this happening again.
