I have a sharepoint test page. I inserted my webpart earlier before my development, but after a period of time now I find that when I click "edit page", the "loading" tag will run forever and I cannot edit my page.
Then I tried to type "?Contents=1" after my page url, delete the webpart and re-add it. When I tried to save my changes, the "saving" tag also runs forever.
Such issue only happens to my webpart. I tried to use other webparts and they works perfectly. Any one got some idea?
