WP HTTP Error: Couldn't resolve host

    I’ve got a brand new install of WPMU on a server here with no plugins or any data to speak of. When I go to the dashboard home page I’m getting the “WP HTTP Error: Couldn’t resolve host” in the www.ads-software.com RSS feeds section. I can’t add rss feeds in the sidebar widget either. nslookup, ping, and dig all work fine from that server. Additionally, when I went to install the buddypress plugin by searching for it in the plugin installer in the wp-admin area I got this error: “An Unexpected HTTP Error occurred during the API request.” The section called “Popular tags” on that page (wp-admin/plugin-install.php) was also empty. Any help would be appreciated.

    The Core Control plugin died on me. It claimed “Plugin could not be activated because it triggered a fatal error.” when I tried to activate it in the control panel. I sense that this is a DNS problem as well. We had quite a time with getting our domain controller WIN2003 server to deal up a wildcard DNS entry to that server which seems to be working for everything except the application it was created for…I appreciate everyone’s suggestions. I’ll see what the folks at serverfault and superuser have to say.

    What’s the fatal error? I can’t say I’ve used it on multisite but it should be fine based on my knowledge of it.

    [Edit, I take that back, I’ve used it in multisite, and it works fine…]

    That said, if you’re still running MU (i.e. 2.9.x) and not 3.0 multisite, then yeah, the new version would not work.

    [Edit, maybe download an older tag…]

    The error was only as specific as what I put in quotes up there. It didn’t seem to show up in the apache access or error logs. I tried activating in in both the plugins and the mu-plugins folder as well.

    This is wordpressMU 2.9.2 BTW according to the dashboard footer.

    Another little nugget: I ran the php/cURL script above from the command line since I have PHP installed as a cgi-binary as well and it worked when it doesn’t work from the browser…heh…

    update: I tore down the MU install today and put WordPress 3.0 in its place. I installed the Core Control plugin turned on the HTTP Logging Module and discovered that it was indeed cURL that was having trouble resolving the host names in those widgets and RSS feeds. Still haven’t figured out where the configuration glitch is.

    Glad you could get it working.

    You can disable the cURL transport and hopefully you’ll have luck with one of the others. I’d test them all.

    If none work, then your server can’t communicate to the world and you’ll need to get that looked at.

    I got this message on two of my blogs just today. Something happened overnight. Host is Yahoo.

    WP HTTP Error: Couldn’t resolve host ‘www.ads-software.com’

    There are others issues associated with this too…like Akismet servers are not being found, etc. I called Yahoo since it seems to me (I am not a network geek) to be a server issue?
