Hi, I'm trying to debug the package org2nikola, which works on emacs-24.5 but not on >emacs-25. What I'm trying to see is why the title is exported when using >emacs-25 but not when prior versions. For what I've being testing, it doesn't seem related to the package but to org-mode or emacs. I'll explain why I think this. An example text I want to export would be: ,--- | * TODO Testing :test: | Nullam eu ante vel est convallis dignissim. Fusce suscipit, wisi nec | facilisis facilisis, est dui fermentum leo, quis tempor ligula erat | quis odio. Nunc porta vulputate tellus. Nunc rutrum turpis sed pede. | Sed bibendum. Aliquam posuere. Nunc aliquet, augue nec adipiscing | interdum, lacus tellus malesuada massa, quis varius mi purus non odio. | Pellentesque condimentum, magna ut suscipit hendrerit, ipsum augue | ornare nulla, non luctus diam neque sit amet urna. Curabitur | vulputate vestibulum lorem. Fusce sagittis, libero non molestie | mollis, magna orci ultrices dolor, at vulputate neque nulla lacinia | eros. Sed id ligula quis est convallis tempor. Curabitur lacinia | pulvinar nibh. Nam a sapien. `--- I would execute the function `org2nikola-export-subtree' in the header. More or less, this function would guide us until the next function with the above text, but not the header, marked as a region: ,---- | (org-export-as 'html t nil t) `---- In emacs-24.5 this function returns: ,---- |

| Nullam eu ante vel est convallis dignissim. Fusce suscipit, wisi nec facilisis | facilisis, est dui fermentum leo, quis tempor ligula erat quis odio. Nunc porta | vulputate tell us. Nunc rutrum turpis sed pede. Sed bibendum. Aliquam posuere. | Nunc aliquet, augue nec adipiscing interdum, lacus tellus malesuada massa, quis | varius mi purus non odio. Pellentesque condimentum, magna ut suscipit hendrerit, | ipsum augue ornare nulla, non luctus diam neque sit amet urna. Curabitur vulputate | vestibulum lorem. Fusce sagittis, libero non molestie mollis, magna orci ultrices | dolor, at vulputate neque nulla lacinia eros. Sed id ligula quis est convallis | tempor. Curabitur lacinia pulvinar nibh. Nam a sapien. |

`---- In both emacs versions I have same results until I arribe here. I'm not sure how to proceed to debug, any idea? Just ask me more information if needed. PD: I attach my org-mode configuration since it's what is sugested, but I don't know if it's relevant. I've only removed agenda related variables.
