Thanks for the reply.
Im using version 2.9.3
the full error is this:
WordPress database error: [Column ‘scanlator’ cannot be null]
INSERT INTO wp_comic_chapter
(title
, number
, summary
, series_id
, pubdate
, slug
, scanlator
, scanlator_slug
, volume

) VALUES (‘Venom Spines’, ’14’, ”, 12, ‘2016-03-02 22:43:33 +0000′, ’14’, NULL, NULL, 0, ‘/UO/14/’)
I think you’re right about a different plugin causing the problem.
It must be Kommiku Viewer’s fault!
