Posso accedere al latopubblico del sito. Ma la dashboard viene visualizzata vuota.

Il registromostra unerrore chepunta alplugin RevSlider:

 PHP Fatal error:  Uncaught Error: [] operator not supported for strings in /var/www/html/wp-content/plugins/revslider/includes/framework/base-admin.class.php:141

Ecco latraccia completa:

 #0 /var/www/html/wp-content/plugins/revslider/admin/revslider-admin.class.php(1143): RevSliderBaseAdmin::addMetaBox('Revolution Slid...', '', Array, NULL)

#2 /var/www/html/wp-content/plugins/revslider/admin/revslider-admin.class.php(87): RevSliderAdmin->init()

I can access the public side of the site. But the dashboard comes up blank.

The log shows an error pointing to the RevSlider plugin:

PHP Fatal error:  Uncaught Error: [] operator not supported for strings in /var/www/html/wp-content/plugins/revslider/includes/framework/base-admin.class.php:141

  This might not be appropriate here, but was most useful to me as this error made accessing the admin completely unreachable after a PHP upgrade, and fixing it was not a matter of debugging what happened but just applying the hotfix from the accepted answer.

Sono statoin grado di correggere l'errore correggendoilplug-in RevSlider sulmio server come documentato qui .

In revslider/includes/framework/base-admin.class.php,ho cambiato la seguente riga (l. 21 dellamia versione) da:

 private static $arrMetaBoxes = '';         //option boxes that will be added to post

a:

 private static $arrMetaBoxes = array();    //option boxes that will be added to post

I was able to fix the error by hotfixing the RevSlider plugin on my server as documented here.

In revslider/includes/framework/base-admin.class.php, I changed the following line (l. 21 of my version) from:

private static $arrMetaBoxes = '';         //option boxes that will be added to post

to:

private static $arrMetaBoxes = array();    //option boxes that will be added to post

Puoi usare "[]"invece di "array ()".

You can use `[]` instead of `array()`.

Hi thanks for this answer! In my case, I was using the churchHope wordpress template, and was getting an error on /churchope/lib/revslider/inc_php/framework/base_admin.class.php:72 - fixed this by changing private static $arrMetaBoxes = ""; to private static $arrMetaBoxes = array();

Ti devo unabirra.+1e per la spiegazione,in php7 hai restrizionipiù strette suitipi,quindi una stringa vuotanonpuò avere qualcosa aggiunto adessamentre latratta come un array.Comemenzionato da @fuxia,`[]`funzionabene anche quied èpiù Pythonish.

I owe you a beer. +1 and for the explanation, in php7 you have tighter restrictions on types so an empty string cannot have something appended to it while treating it like an array. As @fuxia mentioned `[]` also works here well and is more Pythonish.

We encountered this error today when migrating to PHP 7.3 and this hotfix worked perfectly. As @AlessandroMattiuzzi mentioned, the path appears to have changed in recent versions of the plugin.
