I upgraded from 1.7x to the current limesurvey200plus-build121213. When upgrading the database I got the following error:
An non-recoverable error happened during the update. Error details:
CDbCommand failed to execute the SQL statement: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'parent_qid'
Please fix this error in your database and try again
What do I need to do to fix this?
