Unfortunately.. this bugs a bit more :-(
When i made a fresh install of this plugin on one of my test site,
This is having some DB error.
WordPress database error: [Table 'mydb_name.wp_em_ess_feeds' doesn't exist]
SELECT COUNT(*) FROM wp_em_ess_feeds WHERE feed_status = 'ACTIVE'
... and similar for feed_status = 'DELETED' etc.
Also i tried importing with above urls you gave
but that gave the similar error i mentioned at top (now the red text is 1.4 instead 1.2 )
Thanks for the time you guys are giving into.
