Buon pomeriggio,
ho dovuto fare installazione di drupal 9, e poi aggiunta del tema bootstrap-italia
il tutto seguendo questo link
https://git.drupalcode.org/project/bootstrap_italia/-/blob/8.x-0.x/READM...
Ho installato correttamente drupal 9 e caricato il tema con le sue librerie.
Però da quando ho caricato il tema, drupal non funziona correttamente, mentre prima di installazione
di tema era ok, funzionava. Un primo errore l'ho risolto installando un modulo beta per il tema di
bootstrap-italia per la precisione questo:
https://www.drupal.org/project/components/releases
ho dovuto prendere la versione beta3 ultima dato che è compatibile con drupal 9.
Però cosi facendo ho visto, che il problema che avevo prima sui componenti è stato risolto, mentre adesso
ho il problema che lato amministratore, quando clicco sulle sezioni principali del pannello, tipo
Struttura, Contenuto o altro non mi carica nessuna pagina ed ho il seguente errore:

e se eseguo il comando composer require drush/drush ho il seguente avviso invece
Package container-interop/container-interop is abandoned, you should avoid using it. Use psr/container instead.
Come devo fare, non ho capito ....
Grazie mille
