Support » Plugin: Query Monitor » PHP Fatal Error: Call to undefined method QM_Util::shorten_fqn()

  • Hans Schuijff



    Today I noticed some fatal errors in my php log related to your plugin. Perhaps something that needs your attention? All plugins and wp-core are updated to the latest versions and php version is v7.2.6

    [18-Jul-2018 08:40:35 UTC] PHP Fatal error:  Uncaught Error: Call to undefined method QM_Util::shorten_fqn() in /home/nginx/domains/
    Stack trace:
    #0 [internal function]: QM_Backtrace->filter_trace(Array)
    #1 /home/nginx/domains/ array_map(Array, Array)

    Thanks for the message! Do the errors still occur or did they only appear at the point where you updated Query Monitor? I ask because QM sometimes causes this sort of error at the point where the plugin update is performed.

    Hi John,

    I think the answer on your question is Yes they still occur. I’m not always sure, because of the log-timestamp is so different than my local time, but when I look into my current log today then:

    The first has timestamp:
    [18-Jul-2018 08:40:35 UTC]

    and the last has timestamp:
    [18-Jul-2018 17:16:52 UTC]

    and the same error occurs in the log a total of 13 times from the first to the last.

    When I noticed the error, I deactivated the plugin, so for that reason I wouldn’t expect it right now, but the number of occurrences and the time-span between would probably suggest it to not only occur on update. As far as I remember there has been only one update yesterday or so.

    Hope this helps.

    Thanks, Hans
