A network subsite inaccessible after 3.5 upgrade

Hi,

This is probably a tricky one for you to respond to, but I will try anyway. After upgrading our multisite install yesterday at http://mediajungle.dk, I had a call from a user in distress this morning. His subsite http://pesticider.mediajungle.dk doesn’t show up in the browser (the title loads though). Attemps to access the site’s admin leads to an error page

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

.

http://pesticider.mediajungle.dk/wp-admin/

As super admin I can’t access the site’s dashboard either, only the superadmin settings pages.

I also upgraded several themes in our installation yesterday. This particular site uses the theme Blaskan. I thought the theme might be the problem, but other sites running Blaskan seem to be fine (http://embordtennis.mediajungle.dk).

I could try disabling all network plugins, but I am using Pro Sites Plugins to manage plugin availability for local sites (we have aroud 3000 local sites in this installation), so most plugins are already network disabled.

Would you have any suggestions?

Regards

Kristian

    Hi Kristian,

    This may be a silly question, but when you updated the core and themes, did you also update the network? Can you get to the dashboard of the site? I can get to the login screen, but if I go to the site, I get a whitescreen. This suggests a plugin issue, WSOD, ie White Screen of Death! What a horrible diagnosis, eh? If you can get to the dashboard, disable the local plugins and then, if no good, change the theme to 2012.

    Hope this helps! Let us know how it goes.

    Cheers,

    Paul

    Hi Paul,

    Not a silly question in my case :slight_smile: But yes, I did update the whole network as well. It makes sense to try to disable the local plugins of the site in question – but is there any way I can do that without access to the site’s dashboard? I know how to force-change a local site to use theme 2012 via superadmin’s network site overview, but not how to disable local plugins (and I don’t have the skills to touch the individual site’s mysql database settings).

    Regards

    Hi there,

    What I was thinking was that you could log in as Super Admin, or rather go to:

    http://pesticider.mediajungle.dk/wp-admin/plugins.php

    And if you get here, just deactivate all the plugins that you see activated. As I said, it’s not clear that you’d be able to get there, but if you could that’d be great. If not, what Ashley suggests above is possible, but that will affect the whole network, which I understand is something that you don’t want to do.

    Cheers,

    Paul

    OK, I went ahead an renamed the folder wp-content/plugins temporarily, and it worked. Once all plugins were “unreachable”, I was able to access the site’s dashboard as well as the frontend. Even though the site’s dashboard-list of plugins just showed a red marked full list of inaccessible plugins, I went ahead and disabled (the empty list) of all the site’s plugins. Now it works. I still don’t know which plugin caused the problem.

    But many thanks for the help :slight_smile:

    Thats ok but bear in mind that all the plugins are deactivated now so all you need to do is rename the plugins folder back to the original name.

    Now go through and activate each plugin one by one until you receive the same problem. Then you will know which one is causing the problem and therefore address the plugin author with the issue.

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
