Cannot Edit Dashboard/Manage

I have Connections installed which was working perfectly. I then added the extensions Widgets/Form which didn’t cause any problems. However, when I have re-logged into the site the entries that were showing in Dashboard/Manage are there as a count but the entry is not showing and therefore cannot be edited. See the screenshot here –

Please advise what to check/do
