This standalone sitemap generator script is really a timesaver, not only when it comes to creating sitemaps but also finding broken links and inspecting the site structure. It also keeps a log of changes – new URLs that’s been added and URLs removed from the site.

I’ve been working on an enormous site recently and wouldn’t get by without this tool – it found all broken links (about 800 of them..ugh)

This error appears when you try to submit an initial recurring transaction to PayPal’s Payflow Pro gateway.

I was puzzling over this issue for days and had no clue why it was happening. The form worked fine most of the time, and once in a while I would get this error. A similar setup for one of my other clients worked fine 100% of the time. So after some googling and code-digging I found the root of the problem: the “ProfileName” field was being dynamically generated, and if it had strange characters, like “&” (ampersand) or was too long, that would trigger the Start/Nextpaymentdate error (because the “Start” field immediately follows the “ProfileName” field in the string sent to PayPal). To fix this, make sure your “ProfileName” value is something static, like “MonthlyPayment”. That should take care of this.
