One site on the network becomes unreachable

  • Hi,

    I have one site on my network of 9 sites that becomes unreachable.
    When logging into the dashboard it first displays that there are no posts or pages.

    Then I suddenly can’t login into the dashboard. When I look at the database tables for the site, all the data is still there.

    I have an error log file but I don’t really understand how to decipher what the issue is.

    What I find strange is that it is only affecting one site. I’m not ruling out a plugin conflict… but it without turning them all off and leaving the site for a week.. I’m not sure how i can identify which plugin is causing the issue.

    The error only seems to happen after about a week. I don’t know how I can find out which plugin is trying to auto-update.

    Any help would be much appreciated.

  • Try changing the site’s theme( stylesheet and template) to twentyeleven in the edit site section of the network admin dashboard. You’ll have to change ‘stylesheet’ and ‘template’ to ‘twentyeleven’

    I am unsure why but I am forced to do this every time I create a new site on the multisite because I run into the same problem you are having.

    So I have to simply activate the Twenty Twelve theme for the problem site, then switch it back to the theme I am using?

    Do you know why that is exactly?


    Did you guys change the default theme for new sites in your wp-config?

    Hi Ipstenu,

    I wasn’t aware you could change the default theme for new sites…
    I only have Twenty Twelve activated on my network.
    Are you able to help decipher my log file?


    I wasn’t aware you could change the default theme for new sites…

    Probably means you didn’t do it then 😉 Don’t worry about it.

    If you post your error log, we can give it a shot.


    Thanks for getting back to me.

    error log can be found here:

    I have put two files in there. One from when I went weird and one from the past week or so…

    Thanks for your time.

    I would ask your host if there have been timeout issues with your database, because that looks like one problem.

    But also you have this:

    [31-May-2013 06:07:08] PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 138488 bytes) in C:\inetpub\wwwroot\wp-includes\wp-db.php on line 950

    So it really looks like you’ve got a wild memory error going on.


    Our IT Admin has looked at the timeout issue, which I think might be related to the timeout issue. He has made some changes to the MySQL to increase its memory usage. However, the issue happened again, and now one of the sites has become unreachable.
    When I try to go to the the site (www.aspireplatform.com) I just get redirected to the wp-login.page

    It seems the main site has become unresponsive too.


    Hmmm scrap the idea of the main site being unresponsive… It seems ok… But one of the sub-sites…still can’t be reached.

    Any help would be much appreciated.


    What plugins are you running?

    I have quite a few that are network activated but listed below are just the ones that are activated on the dead site.

    jQuery lazy load plugin
    LayerSlider WP

    Our It Admin looked into the error log (which is now 1.3gb!) and said this
    “The error I am seeing indicates that it is to do with “jetpack_clean_nonces” and “clean_cache_event”. I suspect that something is submitting a 1 million character query”

    So I disabled the jetpack plugin, which was network activated…but this had no effect.

    The next plan is to restart IIS and MySQL.


    I have just tried to access the site again and then looked at the log file…
    this can be downloaded here:



    IIS… You didn’t mention Windows.

    Ugh. Well you just knocked down the number of people who are familiar with your setup by about 80% :/ Not many of us use IIS, and far fewer use it with Multisite 🙁

    Try running a repair on the DB if you haven’t already. Also optomize it, and how big is wp_x_options for the site that keeps crashing?
