Zitat:

Hallo,

ich habe gestern bootstrap für Contao installiert und wollte nun ein Spaltenset in einem Artikel erstellen. Dabei kommt zuerst diese Fehlermeldung:

Code:

---

Warning: array_keys() expects parameter 1 to be array, null given in composer/vendor/contao-bootstrap/grid-editor/src/DataContainer/ColumnSet.php on line 135
#0 [internal function]: __error(2, 'array_keys() ex...', '/Users/jan-dirk...', 135, Array)

#8 {main}

Und dann, wenn ich auf den Zurück-Button des Browsers gehe, diese oberhalb vom Backend-Fenster von Contao:

Code:

Ich habe sowohl die Erweiterung Subcolumns von Felix Pfeffer als auch Semantic_html5 installiert, aber trotzdem kommen die Fehlermeldungen.
Was habe ich vergessen, wo liegt mein Fehler?

Danke

Der Fehler war, dass ich in den Einstellungen nicht das Spaltenset auf Bootstrap 3 umgestellt habe. Nun scheint es zu funktionieren...
