Change a long text field to text I'm trying to convert a long-text field into a text-field. The only thing I found so far is the "field_config" table in the database. But any change there is only leading to errors. Do I have to change it somewhere else?
Thanks to Geoff. As my long-text never was bigger than the textfield size (255) I could use this solution with ease. I did it the following:
Created a new field "textfield"
Did a database action:

INSERT INTO newtable (newfields)
SELECT oldfields FROM oldtable


and then deleted the old field.
