    Hello forum, perhaps someone can shed some light on this..

    Modx shows a distorted manager page with an error on top when creating a new resource:
    "[onDocFormPrerender] Undefined variable: urls in /path/to/core/cache/includes/elements/modplugin/[seotabPluginId].include.cache.php on line 71"

    Looking into the plugin-code the only way, url may not be defined happens when the return of $modx->event->params['resource'] casts to false. on line 49

    As a quick fix I replaced
    on line 71. But may only cover a symptom.

    This error first happened after Upgrading Modx to version 2.5.8. SEO Tab Verison 2.0.4

    Any ideas?
