unable to enable a power-up

Hi everyone! I'm new to Trello and am now trying to enable the Show Checklist power-up on a board (as the only power-up). It lets me add the power-up but then the power-up doesn't work and I get the following message: "Subscribe in power-up settings. No valid licence found." What do I need to do differently?
I am using the desktop app. I also got this message when I tried to do the same on MS Edge.

Hi @Mikkel Rubæk ,

Welcome to the community! We are glad you are here!

Wish you a very happy new year!

You have to disable the power-up and when you enable it again it asks you to authenticate!

Hi @Soumyadeep Mandal 


I have found the solution! @Polaris Koi I have allowed all third party cookies, a solution I am not very fond of. But now it works.

Hi @Polaris Koi & @Mikkel Rubæk ,

Sometimes cookies & adblockers are also causing problems! So try to change some settings sometimes and it will work fine! But anyway we are here to help you out!

Hi @Polaris Koi 


I have exact the same problem, and I can't find the right place to authenticate...🤔 

following this thread :-)




Hi @Polaris Koi ,

Welcome to the community!

I think you have to authorize your account with this power-up and I think it also requires a valid licence to use the power-up! You have to connect your account with Show Checklist power-up authentication!

I'm not sure but I think it also requires a valid plan to use the power-up!
