Get 500 internal error by submit changesOpera add-ons
I successfully uploaded new version of add-on but can't submit changes to moderation. Still get 500 internal errors and tried it many times.
Also, I did a test - found version of add-on that published by store, download it and just patch version. This add-on also gets an error on submit changes.
You can see result below.
Hot can I submit a new version of add-on?
