Fatal error in traceErrorMsg() on PHP 7.1.

  • Hi folks, one of my users encountered an error on a site that uses WPML (for multi-lingual pages) and OSM plugin. While creating a new translation of a page at /wp-admin/post.php?post=2&action=edit&lang=en they encountered a fatal PHP error: Fatal error: Uncaught Error: Using $this when not in object context in .../wordpress/wp-content/plugins/osm/osm.php on line 249 which was triggered by this OSM error: [OSM-Plugin-Error]:Array hast got wrong file extension (gpx, kml)!. While there may be other conflicts with these two plugins, fixing the fatal PHP error in the OSM plugin allows the editor to load successfully on PHP 7.1.29 even though the OSM error flashes a bit.

    Here is a patch to fix the fatal error in the OSM plugin:

    diff --git a/wp-content/plugins/osm/osm.php b/wp-content/plugins/osm/osm.php

    $EMsg = $this->ErrorMsg->get_error_message($e);

    Upon further investigation, this error was triggered by editing an already saved post with an OSM shortcode that includes a broken KML link. I’m not sure how this got saved previously, but having the file_list parameter end in just / instead of an actual filename seemed to initiate the sequence of errors.
