   Format: MarkdownItexAm travelling and not stably online today, so just briefly: It looks like updating any page with an `!include`-command for the entry `mathematicscontents` (e.g. *[[category theory]]*) at the moment gives an error message saying that `mathematicscontents` does not exist. Can anyone see what's going on?

   Format: MarkdownItexI added **!include-command category%20theory** to the [sandbox](https://nforum.ncatlab.org/discussion/344/sandbox/#Item_5) and tested it with firefox, edge and chrome successfully by accessing the sandbox.

   Format: MarkdownItexVisiting the page is fine, but updating (trying to save an edit) still produces the error message for me, saying it cannot find the floating-context menu include-file *mathematicscontents* (which indeed seems to have ceased to exist).

   Format: MarkdownItexThanks! That was it. I have renamed *[[mathematicscontents]]* back to its original title, and now things work again. Something is still strange though, besides the previous spam attack seen in its page history, e.g. that my renaming did not trigger the usual nForum announcement. Will check with the technical team.
