Updated to the current version, started the crawl and ran for a while. Timed-out. I added more time and memory to the configuration and started it again. It ran for a while and then stopped. Now when I try to go to the "Create Sitemap" tab/page ([ External links are visible to forum administrators only ]) I get a 500 error. But the error doesn't show up in the PHP log.
Could an .htaccess file be blocking the crawler and throwing it off? If so, how can I find how where it's getting held up?
