I have been using the Free Online Sitemap Generator for a number of years on the same website. Recently however, it has stopped working and I keep getting the following error code:
An error occured
Request is not originated from xml-sitemaps.com
Please make sure to specify the correct website URL and resubmit your request.
I am using a Mac and I have tried the following browsers: Safari, Firefox and Opera.
What has gone wrong?
