Where to find an error in the database
Check in your forums error log for clues Probably related to a mod.
Url?
Smf version?
Mods Installed?
I found a hint that some formspring has no default value but I can't find this column in the database.
That looks like a mod error. You can use this query to find column name, then set it to 'null' -
SELECT table_name,table_schema
FROM INFORMATION_SCHEMA.COLUMNS
WHERE column_name='formspring'

The 'formspring' column in the smf_members table is created by the Formspring Profile Field (https://custom.simplemachines.org/mods/index.php?mod=2677) mod.
