问题
I use xmlsitemap module and I need to change frequency option, so I tried to apply the patch https://www.drupal.org/node/1811692, the patch was applied successfully, but in this case after I got an error with sitemap generation, when I try rebuild sitemap
What's wrong? Is there any way to fix it?
