Trello - BigPicture Power-Up not activating

I am trying to install BigPicture for Trello. It shows up on the task bar, but when I try to activate it, it just repeats the authorization phase. Does anyone know how to resolve this issue?

Hi Topher,

Your inquiry was analysed by our BigPicture Trello Team but for the sake of clarity for others who can read this post please be informed that: 

  • We currently support web-based Trello Power-Up only, so the following ones are not supported:
  • Users utilizing Trello paid options: Trello Gold, Trello Business or Trello Enterprise may experience the Gantt chart not being loaded. Together with Trello we are working on fixing this issue.
  • The next BigPicture Power-Up bug-fix release is planned for 35th Week (August 27, 2018 - September 2, 2018). 
  • We have a Public Roadmap that can be found here.

Hi Radoslaw

I have the same problem and already tried 3 different browsers.

As soon as I clicked on allow, I receive an empty page: .......


Do you have any suggestion what could be the problem?

Best regards

I'm thinking this might be a server problem for softwareplant (developers of the plugin), I have the same issue, and also noticed that the 'view agreement' and 'view privacy policy' links throw out a proxy error atm :

I'm going to give it another go tomorrow.

up, the whole wiki.softwareplant domain was out earlier as well.

fwiw, the wiki is back up, but still seems to be having trouble...


edit: actually, its working again, just need to remove and re-add the power-up (otherwise it just pops up the white screen again)

Thanks Mark, stupid question, how do I remove the power-up? I can't seem to access any way to remove power-ups.

Okay I seem to have come right with removing and adding - still not getting decent data in the Gant, I'm sure I'll figure it out.

It works now thank you :)

Hi there! I was struggling with the same issue. And the reason was that I was not the board owner. So, let’s get this straight: even though I had “admin” level user rights, big picture won’t work. Only when I created the board myself.

I tried changing browser, computer OS, etc. nothing worked.

I believe this bug could be investigated further by big picture team!

Hi @Rodrigo Lobato

Please, contact our Service Desk. It is the fastest and the best and fastest way to investigate the issue. Thank you.

Hi Anna, thanks for you recommendation, but as mentioned I already solved the issue. Administrators won’t be able to implement the plug-in, board owners will.

I believe this is either a bug or if it was intentional, than it would be better to change the alert message to something like “only board owners can authorize big picture”.

@Rodrigo Lobato

The power-up behavior you described in your post is not expected behavior, and we would like to fix it. Therefore, if it's not a problem, please contact our Service Desk, providing more details (Dev Console report).

Hi @Ilkhom

I am sorry to hear that you experienced this inconvenience.
We will need more information to diagnose your problem properly and introduce a solution.

Therefore, I would like to ask you to raise a ticket via our Service Desk, allowing our product specialists and developers to investigate your instance and BigPicture power-up further.

We would be grateful for the following additional information in a raised Service Desk ticket:

  • Please try accessing the app from a different browser (Firefox/IE/Edge, not Chrome or vice versa) from a different network (home, not office, or vice versa) and let us know if the problem persists.
  • Does the error occur for all platforms, PC/MAC/Linux?
  • Does the error occur while using incognito mode?
  • Could you provide the Dev console report?
  • Could you provide the details of the platform and browser you are using?
  • Could you provide the list of browser add-ons you are using in your browser?

Thank you.

Hey Topher, 

Wondering if this is an issue specific to a certain browser of if you've ruled that out already? 

Thanks for your reply - I was trying to activate it via the native app, when I tried through a browser, it worked fine.

Glad to hear you got it worked out!

I'm having exactly the same issue, using chrome browser.

Same issue as the OP FYI. This power-up doesn't seem to activate in the desktop app, it can only be activated online. I used Firefox and was able to activate it first try online.
