I installed all the utilities extensions in my ThingWorx 7.1.1.b24 two months ago. And it went well at that time. But I want to do a demo on Utilities, and start the vm today, the contents of converge mashup is missing. Just as the following pic.
Then I check the ThingWorx Composer, the extension management. Everything is here.
Then I check the application logs. It shows me as the following error.
I don't know how to solve. Can you help me? Thanks a lot.
