I think this is probably a DNS configuration issue with my host, but as they're denying all fallibility I might as well post here... just in case.
For a couple of weeks, both the WP sites that i've done have lost some functionality. When I try to search for plugins I receive an error that says -
"An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums."
And when I'm in the dashboard, 'Incoming Links' and 'WordPress Blog' say things like -
RSS Error: WP HTTP Error: Couldn't resolve host 'blogsearch.google.com'
I've looked around and found all sorts of reasons for such errors, with different people blaming each other, and think i've tried all the solutions on offer -
Deactivate plugins, then back one at a time.
Fresh download and write over all but 'wp-content' etc.
So I thought i'd come here for the first time, before amping it up with my host.
(It really does feel like a DNS configuration issue...)
Here's one of the sites affected, just in case that'll help in any way -
