  • have you created system.xml ? Commented Jan 16, 2015 at 14:01
  • in Xsitemap/etc/system.xml what do use in module="" under xml tag ? Commented Jan 16, 2015 at 14:05
  • Have you defined the helpers node in your Xsitemap module's config xml, and does the helper actually exist? Maybe you mistakenly call xsitemap as helper, where you mean sitemap? As in: Mage::helper('xsitemap')->__(string) instead of Mage::helper('sitemap')->__(string) Commented Jan 16, 2015 at 15:49

I had same issue previously, So i have applied below fixes and it's working properly. I have added helper note on config.xml file and delete cache folder.



You need to create a helper class and add above node on module config file.
