In human language the error means that your sqlite database got corrupted. In some cases it is possible to recover the database but there is no universal method of doing that. You begin with creating an .sql backup file of that database and then you look inside, decide what's wrong, remove it and import the fixed .sql into a fresh database. There is a good chance that it will work. It won't fix itself so if you don't do something - the problem will get worse.
