    I just got the following error:

    Fatal error: Class QM_Output_Html contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (QM_Output::get_type) in /[complete path]/wp-content/plugins/query-monitor/output/Html.php on line 183

    I also saw that error when doing an upgrade on one of my sites, but I made an executive decision to not worry about it. The upgrade is successful and the error only occurs once.

    The reason the error occurs is because the QM_Output_Html class signature changed in the latest update. When the update screen loads, it loads the current version of the class, but after the update has finished and Query Monitor shows its output the classes that extend this class have a different signature, causing the fatal error.

    Bit annoying but I’m not going to worry about it.
