I am working on ECL provider and for starter, I am trying to run Flickr ECL. I have done with all the steps provided in Bart's blog. I am getting Flickr icon on CMS but on clicking on it I am getting this error
/WebUI/Models/ECL/Services/General.svc/GetList failed to execute.
STATUS (500): System.ServiceModel.ServiceActivationException.
I have tried to search the same on net and there was a blog to change some settings in "Metabase.xml".
How can I fix this problem?
