I have a block on top of my page which is showing announcements. I never put it there, it's been there since I installed the suite. I've removed it multiple times, but after refreshing the page it'll still be there. How do I get this announcements block removed permanently? 

I tried clearing the cache but to no avail. Is there a solution for this?

This is an issue I had before - and several others as well. Suggest you file a ticket. I had it as well but my board crashed and after I hired a pro and reinstalled my testboard again it was gone.

 

I wish I had your issue, I have the opposite, my Announcement block always disappears.
