Anytime I open a math/markdown/richtext pad, only the title field is editable, but not the code field. Console shows:

OpenError: The operation failed for reasons unrelated to the database itself and not covered by any other error code.
  0.9547956b.chunk.js:109:10926
UnknownError
  0.9547956b.chunk.js:48:168962

Then when I navigate back to the frontpage:
