After adding the Email for Trello Power-Up to a Trello board, each team member will be prompted to authorise Email for Trello for the PowerUp to work with their Trello account.
Unable to authorise the Power-Up
There may be a number of reasons why you are not able to authorise the Power-Up:
Your browser is blocking pop-ups
You are using an ad blocker
The pop-up opens behind your open windows
We run through a few of these reasons here below.
Trello also provide some guidelines to Troubleshooting a Power-Up that won't authorise and steps for Troubleshooting browser issues
If you've already authorised and the Power-Up continues prompting you to do so, try authorising in a different browser.
If you are still having trouble and none of the solutions below work for you, please contact us at help@sendboard.com for help.
Your browser is blocking pop-ups
Google Chrome
Google Chrome does a great job at blocking pop-up windows out of the box, but sometimes it prevents them even if you’re expecting one from a trusted site.
When Chrome blocks a pop-up from a website, it displays an icon with a red X in the corner of the Omnibox.
If you suspect this is an error and want to see pop-ups from this website, click on the icon to see site-specific options, select “Always Allow Pop-ups and Redirects” and then click “Done.”
After you click “Done,” refresh the page to save your choice and see any intended pop-ups on this website.
Firefox
Select the Menu button. (The menu button looks like 3 horizontal bars located at the top right corner of the browser.)
Choose Options (for Mac users: Start from the Firefox menu then select Preferences).
Select the Privacy & Security link from the left menu.
Scroll down to the Permissions section.
Next to Block pop-up windows, choose Exceptions.
Enter trello.com then select Allow.
Select Save Changes.
Restart Firefox.
Microsoft Edge
Open Microsoft Edge browser. Click on "More actions" link (This is link with three dots (...) at right side on address bar)
In "More actions" menu, Click on "Settings" to open Settings screen.
In "Settings" screen, click "View advanced settings" button below "Advanced settings"
In "Advanced settings" screen, turn ON toggle button below the "Block pop-ups" to block the pop-ups. Turn OFF toggle button to unblock the pop-ups.
Safari
If you know of a specific website that uses pop-up windows, you can enable pop-ups for that particular website rather easily through Safari preferences:
Open the Safari app if you have not done so already, then navigate to the web site you want to enable popups for
Pull down the “Safari” menu and choose “Preferences”
Select the “Websites” tab then click on “Pop-Up Windows” from the left side menu
Locate the website URL in the list, then click the dropdown selection menu next to that URL and choose “Allow”
Close Safari Preferences
This is a great approach because it allows you to block all general pop-up windows in Safari, while allowing them on specific websites that you know require the use of pop-ups to function properly.
You are using an ad blocker
Adblock
To always allow pop-ups to show on the page you're currently viewing, click the AdBlock icon in your toolbar and select Don't run on this page. This creates a whitelist rule in AdBlock.
Whitelist rules are also known as exception rules—or sometimes exclusion rules—because they tell ad blockers to make an exception for or exclude whatever the rule refers to.
AdBlock will not block ads on the current page but will still block them everywhere else, including on other pages on the same site.
Adblock Plus
To always allow pop-ups to show on the page you're currently viewing, click the AdBlock Plus icon in your toolbar. Click on Enabled on this site, and it will change to Disabled on this site and the site will be reloaded.
This is when you’ll know that AdBlock Plus has been successfully disabled on that specific domain and all of the webpages on it and that the domain has been whitelisted.
The pop-up opens behind your open windows
This rarely happens but it can be annoying when it does as the pop-up doesn't appear when you click the 'Authorise' button.
To check if this is the case, minimise all your open windows to check if the pop-up is not behind them perhaps.
