 * Good morning,
 * I suddenly have errors in my blog. All I have done recently is upgrade the Theme.
   Is it a known problem to you? – and what can I do about it? I assume it relates
   to previous and next blogs, but I do not even have that turned on.

 * SELECT p.ID FROM wp_posts AS p INNER JOIN wp_term_relationships AS pll_tr ON 
   pll_tr.object_id = ID WHERE p.post_date < ‘2014-05-07 10:02:07’ AND p.post_type
   = ‘post’ AND p.post_status = ‘publish’ AND pll_tr.term_taxonomy_id = 6 AND p.
   ID NOT IN ( ) ORDER BY p.post_date DESC LIMIT 1

 * I have not changed or upgraded recently and it just started happening.

 * Hi!
 * The faulty statement in your SQL query is probably `AND p.ID NOT IN ( )`
    I believe
   that it is not added by Polylang. It looks like it refers to some possibility
   to exclude posts but you don’t exclude any.
 * If the last modification you did is to upgrade your theme, I suggest that you
   look in that direction.
