Description of my issue

Many thanks for making this excellent software available to us. Fantastic. I would like to raise an issue that I am having. I’m self-hosted but I am not able to create a Listed account. When I click on create new author it looks like something is happening but it appears to just time out

  • preferences > account settings > Listed “create new author”
  • Click “create new author”
  • Feedback is “creating new account” (greyed out)
  • Returns nothing, the box returns to "create new author

Can anyone help me with this?

Many thanks
