Hi. I am trying to upload a downloaded app, the Page Tree Creator from EPS Software Engineering AG, to attempt to use as an alternative to creating multi-page blueprints (which I had asked here ).
From my understanding, I should be able to upload a file with the downloaded app (a JAR) into my atlassian site via the Upload App option in Manage Apps, but as I try this option all I see is this:
I created this atlassian site myself, so I should have enough credentials to allow for apps to be uploaded, or is it that I have neglected to enable any options? Under settings, I have checked both Enable private listings and Enable development mode, but is there anything I am missing?
Please let me know if there is something I have not done, or if the upload option is even available. Thank you.
