There is a HUGE issue with this MOD.
I have it installed and although it works perfectly fine, I have come across an issue, a BIG issue.
When you enter a PayPal email address, on the add, it will give you a Buy Now button. Clicking it will take you to PayPal to purchase the item your buying. That in and of itself is fine. What happens after is not.
You do not get a redirect back to the add page from the PayPal site after you buy. Nor does the Ad OR the Buy Now button get removed from the Ad. Meaning that during the course of someone actually buying an item, someone else could do so as well. So the item could be bought more than once. Unacceptable if you've only got 1 of an item to sell.
For now, I simply commented out of the MOD using HTML the ability to view the PayPal stuff on ad creation. I really think this needs to be dealt with and Im not sure if the author pays attention to this forum or not.
