I am experiencing a similar issue with version 2.0.2. The config seems to be fine, file permissions all set correctly, but when I go to run the crawl manually from the GUI, I see the message "Please wait. Sitemap generation in progress..." at top and the following in the body:
Links depth: -
Current page: -
Pages added to sitemap: -
Pages scanned: - (- Kb)
Pages left: - (+ - queued for the next depth level)
Time passed: -
Time left: -
Memory usage: -
There are no values added to these fields, and I have yet to experience a browser timeout or any progress in the crawling window after 10 minutes. No sitemap is generated.
I've tried the suggestion you've made here with the saves and setting it for "run in background" with no result. In the config, I am limiting it it to 150 pages, 9000 seconds and save every 60 seconds. This was just to test and see if it was going to actually work.
I'm attempting to run this against a modified PHPnuke site. LAMP platform, PHP 4.3.x Any insight will be appreciated.
