Realised that this is what I have as well (should have read more threads before posting) : https://www.ads-software.com/support/topic/feed-to-post-not-updating?replies=1
Mine is in a subdomain if that is any help? .. Currently trying rolling back versions to see if it works then.
Rolled back my WordPress version, still not working. When I press the CLICK TO GET FEEDS NOW button I get this error after a while :
Fatal error: Maximum execution time of 30 seconds exceeded in \httpdocs\frontpage\wp-includes\SimplePie\File.php on line 116
Could this be a file permission thing? As it may be a problem with my host?
