Online Editor fails to create new file

Hi,

I’ve set up the online editor (free). It’s working fine to view and edit existing markdown files and I can see and use resources without a problem.

What I can’t do is make anything new. If I click on the “+ New File” button I am simply taken to the home page. The javascript console shows an error from index.js line 8:

“Failed to load a resource: the server responded with a status of 404()”. and the file listed is

https://www.curtisfamily.org.uk/undefined

Index.js line 8 simply logs to the console, so something else is going wrong.

Am I unable to create new files with the online editor unless I pay for a licence or is something broken? It’s puzzling as what look like similar functions for edit and saving edited files seem to work fine, which also suggests that the relevant permissions are OK.
