SmartCrawl not showing sitemap

I was getting an error with SmartCrawl where it said that there was an error on line 2, after a plugin and theme conflict test and re-crawling the site and generating the sitemap still go the same issue.

As a workaround used a third party plugin to create the sitemap which worked so tested it again with SmartCrawl but now got a blank page, ran a plugin and theme conflict again but got the same issue even after re-crawling the site and updating the sitemap.

Thanks in advance for your help.
