So i’ve successfully upgraded from 2.4.8 to 3.2.1-4, backup the current file system and SQL database.
And now started upgrade from 3.2.1-4 to 3.3.0-6
Here comes a new problem:
[code: Installer Installer::migrateStaticPagesToNavigationMenuItems]
[migration: PKPv3_3_0UpgradeMigration]
ERROR: Upgrade failed: DB: SQLSTATE[22004]: Null value not allowed: 1138 Invalid use of NULL value (SQL: ALTER TABLE authors CHANGE publication_id publication_id BIGINT NOT NULL)
Here is what the null values like in the table authors:
These looks like dummy email addresses added in quicksubmit plugin in the 2.4.8 version.
My question is: Will delete all entries in the author table where publication_id is NULL solve the trick without further problem or it is totally not safe to do so? maybe these author entries are still useful in the system? i have no clue. Please help. @asmecher
I’ve been searching in the forum haven’t found a similar question.
Thanks in advance.
