In the could/hosted version of Invisioncommunity, I have a permanent alert notice on the Applications menu but none of the applications need updating, any tips on how to fix this?

Update your cache in the ACP -> Support.

You can also click on Check for Updates button on Applications page.

You would need to look again. You have a 3rd party application named "Components" which is showing as having an update

No problem. 🙂
