Having trouble deleting topics?

• Story Topic
• Twitter Topic
• League

 etc

even when they have no content in them...

This is a system setup issue that is related to the database user permission in use by Flow.

The user needs to have these permissions assigned:

ALTER
ALTER ROUTINE
CREATE
CREATE ROUTINE
CREATE TEMPORARY TABLES
CREATE VIEW
DELETE
DROP
EVENT
EXECUTE
GRANT
INDEX
INSERT
LOCK TABLES
REFERENCES
SELECT
SHOW VIEW
TRIGGER
UPDATE
