Found a way through SQL:
UPDATE jivetile SET state='ARCHIVED' WHERE tilename='topMembers';
Don't forget to clear all Tile caches afterwards. Re-Activating is possible with:
UPDATE jivetile SET state='PUBLISHED' WHERE tilename='topMembers';
We implemented this same solution. What we are seeing though is that something is changing our tile back from ARCHIVED to PUBLISHED again. If anyone else has run into this issue and pinpointed what is causing the problem do let me know.
