You need to authorize your Twitter accounts.

Did you follow the directions in the “General Settings” box (wp-admin -> settings -> Twitter Widget) for setting up your Twitter application and filling in your consumer secret and key? Several people have left the “Callback URL” field blank during that process, which won’t work. Set the Callback URL to a valid URL (like your site URL).

Yes , the consumer key and secret key, a;p tthe callback url
Bye the way thank you for your quick response!

Someone in another support thread had to reset the key on Twitter:

Can you give that a try?

Hello, I also am having this problem, I’ve tried to reset my keys. Remaking the application on the page.

Please help, this message ‘You need to authorise your Twitter accounts’ is driving me crazy, as my Twitter feed has disappeared from my home page.

When I go into General Settings, I get Consumer Key and Consumer Secret with the fields filled in, no instructions, no line saying Add a New Twitter account… it doesn’t take me to Twitter.

I have tried deleting the plugin re-installing, deleting the widget in Twitter.

Nothing makes any difference please help!

I have now re-set the keys in Twitter, from the previous support thread, and also added the callback URL as that seemed to be the problem. Now the problem is when I click on ‘Authorise New Account’ it takes me to a screen which says

You do not have sufficient permissions to access this page.

Please help.
