MySql Query very slow

You must use a temporary table and an alias: SELECT SQL_CALC_FOUND_ROWS * FROM meruca_posts WHERE ID NOT IN (SELECT ID FROM ( SELECT object_id as ID FROM meruca_term_relationships WHERE term_taxonomy_id IN (14) ) AS temp_object) AND post_type=”post” AND post_status IN (‘publish’,’private’) GROUP BY ID ORDER BY post_date DESC LIMIT 0, 10

Custom query AFTER rss fetch_feed not working

The error seems to be connected to the rss url itself, if I use ‘http://seko.se/feed.rss?rssId=97‘ I can’t create new loops beneath it but if I use another url such as ‘http://www.wpbeginner.com/feed/‘ It works. My original feed works just fine in other readers so I have no idea why it does not work in wordpress.
