I just bought a website which is full of the paypal payment buttons with different values that links to the previous owner info. Now I want to update these information to use my account instead of his, I know how to get a payment code from my paypal account but I just couldn't find an easy way to update all these links on my website (around 500 links) to use my info. I was thinking to use a find~replace program to replace all occurrences of to be updated to but I think it is not that easy, any idea how can I best achieve this ? thanks.
