Conflict with posts 2 posts plugin

After I deactivated the NextGenGallery plugin, my site gone down.
This is an error from error log:

WordPress database error Unknown column ‘ids’ in ‘field list’ for query SELECT wp_posts.*, wp_p2p.* FROM wp_posts INNER JOIN wp_p2p\n\t\t\t\tLEFT JOIN wp_p2pmeta AS p2pm_order ON (\n\t\t\t\t\twp_p2p.p2…

Which means there are a conflict with posts 2 posts plugin.

But why all my site is broken?

What are we going to do to restore the website functionality? I appreciate any good suggestion from wordpress community and especially from nextgengallery team

Having a conflict with Post2Post plug-in too. Associated posts won’t display on the live site (admittedly this could be a theme issue), but in the admin the associated posts aren’t displayed – it shows that there aren’t any. When trying to “reconnect” the association, the plugin says I cannot make duplicate associations.

And, after connecting posts and publishing them, the association isn’t displayed when returning to the post to edit.

Post2Post recognizes the connected post, it’s just not displaying it in the admin. Nor are the connections being displayed on the live site, though as I said, this could be theme related, but I suspect it’s not.

Add Post2Post to the list of known conflicting plugins.
