Resolve a Javascript/PHP Issue - NaN Error

Hi All,

We have been alerted to an issue on our website, [login to view URL], whereby when a user increases the quantity of a product they would like to purchase, the price changes from a number e.g. £23.99 to NaN

This is happening on all product pages, for example here: [login to view URL] and you can re-product the issue by hitting the + button next to the quantity

The website is based on PrestaShop, version but it maybe an addon/module that is causing the issue. Please feel free to forward any questions that you may have.

We are hoping that someone can fix this in-browser without server access and then provide us with instructions on how to fix permanently. Of course we are happy to pay for your services first!

All the best,
