Internal Error beim Anlegen von Inhaltselementen und beim Löschen

**kiekes** · 20.06.2023, 16:49

Hallo in die Runde, ich habe auf einer Testumgebung eine Contao 4.13.24 installiert und quasi ein Update einer Seite von Contao 4.4.57 durchgeführt.

Beim setzen von neuen Inhalten auf hinzugekommenen Inhaltsseiten erhalte ich nun beim Anlegen von Inhaltselementen und zum Teil beim Löschen von Inhaltselementen folgende Fehlermeldungen:

Fehlermeldung beim anlegen von Inhaltselement "Galerie":

Internal Server Error
Was ist das Problem?
Contao\CoreBundle\EventListener\DataContainer\Temp lateOptionsListener::handleLegacyTemplates(): Argument #1 ($type) must be of type string, bool given, called in /homepages/6/d760555275/htdocs/contao4neu/vendor/contao/core-bundle/src/EventListener/DataContainer/TemplateOptionsListener.php on line 62

------------------------------------------
Fehler beim löschen von Inhalteselementen:

Internal Server Error
Was ist das Problem?
count(): Argument #1 ($value) must be of type Countable|array, null given

Inhaltselemente wir Text, Überschrift, Bild kann ich setzen ohne Fehlermeldung.

Hat jemand eine Idee? Ich bin Mediendesigner und leider kein Entwickler, mir sagen die Meldungen nur das in der ersten scheinbar etwas erwartet wird, was in "line 62" somit dann nicht korrekt ist.
Aber es wurde ja an den Dateien von mir nichts verändert?

Contao 4.13.24
Datenbank: MYSQL 8.0
PHP: PHP 8.0

Nutze den Debug-Modus und poste den Stack Trace.

Der Stack meldet drei Dinge, im Frontend. Haben diese dann auch Einfluss auf die Inhaltselemente im Backend?

Soweit mein Verständnis reicht handelt es sich um Datenbankprobleme.
Aber wie beseitige ich diese?

Laut der Fehlermeldung funktioniert die Datenbankverbindung nicht. Lösche mal var/cache/dev manuell.

**kiekes** · 22.06.2023, 14:06

Mit dem manuellen leeren des var/cache/dev ist das Datenbankproblem behoben.
Aber das Problem mit dem internal Server Error wenn ich ein Inhaltselement "Galerie" anlegen will besteht weiterhin.

Fehlermeldung nach Auswahl des Inhaltselement Galerie:

Was ist das Problem?
Contao\CoreBundle\EventListener\DataContainer\Temp lateOptionsListener::handleLegacyTemplates(): Argument #1 ($type) must be of type string, bool given, called in /homepages/6/d760555275/htdocs/contao4neu/vendor/contao/core-bundle/src/EventListener/DataContainer/TemplateOptionsListener.php on line 62

Kann das wirklich das Inhaltselement "Galerie" beeinflussen?
Der Slider Revolution wird in einem Anderen Artikel eingebunden und scheint korrekt zu funktionieren, zumindest im Frontend.

**Spooky** · 22.06.2023, 14:21

Liegt wohl an cfg_slider_revolution - vermutlich eine veraltete Extension.

**kiekes** · 22.06.2023, 15:09

Ja der cfg_slider_revolution ist eine veraltete Version und wird leider auch nicht weitergeführt. Da muss ich mich wohl nach einer Alterative umsehen.

Was mich wundert ist halt, das der Slider die Contao Inhaltselemente beeinflusst. Und ja auch nicht alle, sondern speziell die Galerie.
