Issues with Opera 50

[kenodegard]

I previously used this extension with my Trello boards on Google Chrome but I recently switched to Opera.

The Opera extension appears to be trying as the checklists generated by the extension (in Google Chrome) do not show up unless I disable the extension however neither the parents nor children are displayed properly.

I'm using Opera 57 and the extension isn't working at all. I don't see the extra button to add the parent/child relationship. (It was the same in Opera 56.) Anyone else having this problem? Could it be a conflict with other Trello extensions?
