Upgraded from Xenforo 1 to Xenforo 2 and now I have database problems. On top of that I have to now pay out of pocket for the fix... They charge for errors caused by the program, even if it's on their end. I personally can't recommend this to anyone because of this.
I've been developing a new site using this plugin and it's a fantastic idea for Xenforo. [XFA] offered a discount when upgrading to XF2 edition after purchasing the XF1 copy. Very easy to use with good features, this is a lifesaver if you are trying to build a simple digital shop without going with other systems such as Shopify, Woocommerce etc and then having to mess with bridges.
Being able to integrate a license/product/service shop while keeping everything unified with Xenforo's member, category and permission system is huge. Great work!
The addon works as intended just wish it was more clearer when adding the sale percentage, and maybe updating the FAQ if you haven't done so yet, but overall awesome addon and also the support is great.
