I tested the free sitemap generator and it worked great (with the exception of the 500 page limit of course) so I bought the unlimited version and installed it. However, after about a minute it simply stopped crawling and froze up. So I read your support section about the php.ini settings. Unfortunately, my hosting company limits me to:
memory_limit = 96M
max_execution_time = 45 (seconds)
This is likely the problem. Is there a workaround to this? If not, I will need to ask for a refund.
P.S. Since the "free" script works great, why not modify that software/approach to return the full sitemap report to a customer? You could still charge a fee (for an account or per run). Thanks. I really like your products, just wish they would work.
