Do you find the errors always, or once in a while?
It’s the first time it’s happened – the blog is appox 2 yrs old now.
Do you find any other problems in your dashboard?
Yes,
‘RSS Error: WP HTTP Error: Couldn’t resolve host blogsearch.google.com’
also show under the ‘incoming links’ tab.
Try replacing wp-includes from a fresh download of WordPress.
Sorted now Thanks.
Turned out to be a corrupt file – web host ran a backup and now running smoothly.
We have been seeing an increasing number of customers who have this issue. After checking, we found that the issue was not a plugin (even though activating one of the plugins caused this issue) but it was a RLimit that hostgator implement which was causing the issue. It seems that once a limit is reached, all connections are blocked.
This explains why it is not just one connection or location being effected.
Unfortunately, hostgator do not seem to check the RLimit unless you actually force them to do so.
Hope this helps others with a similar issue.
