Olaf24 on "[Plugin: Content Aware Sidebars] Database error: [Unknown column 'mt1.meta_key' in 'where clause']"

Now I have no child pages at all (only top level), but the error does still occur in this single project.

I can send you the complete project to your website-mail-adresse, if you want: WP-Project and Database-Export. Does that make sense to you?
