   Format: MarkdownItexI have tried to create a page [[derived limit functor]] (and tried few other titles [[lim^n]], [[pokus]]... with the same outcome) with various level of content and every time it returned 500 Internal Server Error. I could edit an _existing_ page just minutes before without a problem. I mean the system prompts the entry box when I call for a new page, but when I want to make the first save then the internal error.

   Format: MarkdownItexThank you, Adeel. After your intervention I could create some pages but now using the search box from a regular page produced the same 500 Internal Error page. Latest Revision button does the same.

   Format: MarkdownItexShould be back to normal now. I was converting the database to utf8 encoding behind the scenes and this had some unexpected consequences.

   Format: MarkdownItexIf at any time in the future, you find that you can edit an existing page but cannot create a new one, then you can effectively create a new one by renaming something from [the list of empty pages](https://ncatlab.org/nlab/list/empty). (You can also do that in any case, of course.)
