Just installed the script. If I limit it to a directory with a few html files and a couple of subdirectories, it produces a great sitemap.xml file. There is a blank ror.xml file with the same permissions as the sitemap file (and the ror.xml create checkbox is checked), but no ror.xml file is created.
If I remove the limit and let the script cruize my site, it will get to the ecommerce section and seems to slow way down and eventually produces the following message:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.
More information about this error may be available in the server error log."
Each time I "restart from where it left off", it does index a few more pages.
Ideas.
