Support » Plugin: Postman SMTP Mailer/Email Log » 503 on active site when installed on multisite

  • I’m posting this as a new issue, but it comes from the thread related to multisite features. I have done a little more debugging. I can reproduce the problem exactly by:

    Installing the plugin on multisite.
    enabling for one site only.
    activating on that site.

    The site immediately reports a 503. Other sites remain working.
    If I go back into the network admin, I can remove the plugin and the site with the problem comes back up.

    I setup debug – there are several lines referring to postman in the apache logs. Basically they repeat the following over and over:
    ‘[Thu Oct 15 18:30:42 2015] [error] PHP Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method msrtm_functions::msrtm_links() should not be called statically in /home/location obscured/public_html/wp-includes/plugin.php on line 213, referer: http:/’

    I’m not sure what this might indicate other than it doesn’t like how a function is being called. I don’t see any errors in php logs, but apache is showing a this string repeating over and over.

    Any ideas what this might indicate? anything specifically could search for in the logs that would be more useful?

    Are you running a plugin called Multisite Robots Text Manager?

    I bet you are. It’s buggy. Deactivate it and then try installing Postman.

    Google is your friend.

    Yes, I was. However, I deactivated it and installed postman, the site where it is enabled went down with the same behavior. No change. I won’t reinstall Multisite Robots but that doesn’t seem to be the cause, or at least it is not the only problem.

    After deactivating that plugin – I tried another test:
    Installed the plugin, activated it on two sites.
    Both sites showed the same behavior – but now I’m not seeing errors being written to the error log.
    Network admin still running fine.
    Uninstalled plugin – we’re back on all sites.

    Things I can say:
    The problem only happens to the sites where it is active. (expected at least)
    The apache errors are gone – but now I’m not seeing any errors.
    The two sites don’t have a lot in common, but I looked at the plugins to see what there was:

    Most of those are multisite specific, but you may have seen them or know they cause conflicts with your setup.

    I really want to thank you for pointing out the problem with Multisite Robots!!! It was wrong on so many levels. But now, I need to figure out what is causing the problem. I am using Cloudways as a hosting provider by the way.

    You keep saying Apache errors. Are you looking at the WordPress log in wp-content/debug.log ?

    What’s your PHP version?

    I have nothing at all in debug.log I mentioned apache errors because that is what I was seeing.

    PHP 5.4.45

    You might have to take this up with Cloudways. Your PHP is simply crashing without any error message, hence the HTTP 503 from Apache. I’ve not heard of this before and it is most likely specific to your particular environment. PHP 5.4 is popular so it must be something else. Perhaps when Postman tries to create its lock file on the file system, there is some kind of security in place that kills the process.

    I’m sorry. It it looks like Postman will not be a fit for you 🙁
