Powerup loading failed - localStorage not enabled even though cookies are excepted
Asked by RJ:

Every time I click on a card I get the following error:

Power-Up Loading Failed {#toc-hId--1182542489}
----------------------------------------------

Your current browser settings prevent Trello from initializing power-ups.

Trello uses the browser to store local authorization settings. Your browser's current settings deny this access.

To continue using Trello power-ups, please follow the instructions for [enabling localStorage access](https://help.trello.com/article/1093-enabling-localstorage). If you need further assistance please contact [support@amazingpowerups.com](mailto:support@amazingpowerups.com).  
[Trello Support Article](https://help.trello.com/article/1093-enabling-localstorage)  
I followed the advice in the link provided. Since I have cookies blocked I added a special exception for \[\*.\]trello.services  

But I continue to get the error. Do I need to close all instances of the browser and restart?

body: I had the same problem - you need to enable third party cookies as well as following their instructions.

It's seems to be in the latest version of the Chrome, Brave, etc.

body: [@Paul O_Neill](/t5/user/viewprofilepage/user-id/1714281) That defeats the purpose of blocking third party cookies and allowing a special exception for Trello, which is what their support page suggests one do.

author: Paul O'Neill
body: [@RJ](/t5/user/viewprofilepage/user-id/4353776) I totally agree but it's the only way I could get it to work in the latest Chrome/Brave browser :(


author: Paul O'Neill
body: I'm on Chrome Version 98.0.4758.102 (Official Build) (64-bit) in case it makes a difference


author: Michael Pryor
body: huh. I feel like my chrome is default version and I haven't changed much and enabling the AmazingFields Power-Up works fine.

oh could it be that amazingpowerups sets their own cookies? There may be a wildcard like \*.amazingpowerups.com or amazingpowerups.com that you could Allow to get that particular Power-Up to work?


author: Paul O'Neill
body: [@Michael Pryor](/t5/user/viewprofilepage/user-id/1131556) I tried that but as soon as I reset Chrome to Block 3rd party cookies I get the same error as RJ


author: RJ
body: Hmm..I noticed a checkbox below the chrome cookie exception option:

"Including third-party cookies on this site".

Checked that for \[\*.\]trello.services just to see if it made a difference but it did not.


author: RJ
body: **Ok, I fixed it. The support page is wrong.**

The error goes away when I add the cookie exception for

\[\*.\]trello.com

Please update the support page or provide correct guidance if this is inaccurate or creates a security loophole.


author: Paul O'Neill
body: Nice one [@RJ](/t5/user/viewprofilepage/user-id/4353776) that worked for me too!

Did you include 3rd party cookies in your exception? I did but would like to remove it if possible...


author: RJ
body: I did. You can remove that and see what happens.


author: Paul O'Neill
body: BaBOING! #fail

Looks like we need to click Third Party cookies on that exception - but at least it works without globally nasty settings ?

This one wouldn't fall under the scope of the program but I'd still send a box of chocolates to each of you if it was up to me :P
