I am using sp 2010. I have a managed metadata global structure implemented. It was working always fine, but today it is empty and gives me this error:
this operation cannot be completed. the term store may be unavailable
When I go to the library which has a managed metadata column. And add a new document the managed metadata tree is empty:
But when I fill in some text in the field it finds some results. I can also save the document.
When I go to the site settings -> Termstore Management Tool I got the error:
this operation cannot be completed. the term store may be unavailable
What is going wrong? Another site collection is working fine.
