Upload my file messages and alerts

Hello Bart,
I’ve downoladed the free version and I think I’ll upgrade to the Pro, since I need the file to be uploaded at the checkout page. But there are two little “but”: the message saying what types of files are allowed for upload says the exact contrary of what I’ve choosen: I choosed to allow the upload jpgs and zips files while the messages says “except jpg and zip”.
Further, I’ve set the max upload size to 10Mb but the alert keep on saying “Max upload size per file: 2MB. Max total upload size: 2MB”.

Last, how can I change the alerts, the error messages and the text buttons into the proper language (italian) ?

Thanks in advance for your attention
