We're starting to use Linnworks and adding our channels.

I have set up the SOAP user and roles and enabled WS-I Compliance and when I click the test button for the Magneto Integration I get a successful test.

When I click the Text Extension I get the message ...

"Cannot load from URL:http://www.myurl.co.uk. Error message: The remote server returned an error: (500) Internal Server Error"

Linnworks help just says this is nothing to do with them.

There are probably only a handful of reasons why this error displays when testing this.

Any one else had this and what was the cause?

We're still on Magento 1.9.0.1 at the moment.
