Hi Christopher and welcome to our :)

Could you try adding ?umbdebugshowtrace=1 to the url? This should show a stack trace and hopefully a more detailed error description will be shown, which can lead to the solution.

Please post the text marked in red in here.

Cheers,
Jan 

Ha, stupid error. 
Thanks for the replies - I hadn't switched to XML in the Data Type! 

Hey Chris,

No worries. It's not the most obvious error. Unfortunately there is not way to know which version you actually want to use so I have to go with the most common, which moving forward will probably be razor, hence why it's JSON by default.

Glad you got it working though.

Matt

@Matt and Jan:

Hi,

I'm just gone through your installation instructions. UmbracoTraceLog says the following:

Hi @Andreas,

You are getting an unauthorised response from Twitter so I'd check that you have successfully authorized an account with the uTwit data type first and that you are passing it the right credentials.

Matt

Hi Matt.

Thank you for your quick response. I am authorized as normal. Unfortunately, I still get always the error. Here are a few screens

The last screen is the log which I have previously written

Hi @Andreas,

It looks like you are using the default uTwit twitter app. It might be a good idea to create your own app at dev.twitter.com and enter the relevant credentials in the uTwit datatypes prevalue. Be sure to follow the guidlines for creating an app carefully, especially around setting a callback url (doesn't need to exist, just needs to be set). Give that a go and see if it helps. I don't tend to recommend people use the uTwit twitter app.

Matt
