Jepeux accéder au côtépublic du site. Mais letableau debordest vide.

Lejournal affiche uneerreurpointant vers leplugin 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

Voici latrace complète:

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

- Celapourraitne pas être appropriéici,mais celam'a ététrès utile car cetteerreur a rendu l'accès à l'administrateur complètementinaccessible après unemise àniveau de PHP,et le corrigern'étaitpas une question de débogage de ce qui s'étaitpassé,mais simplement d'appliquer le correctif àpartir de la réponse acceptée.
  
  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.

J'aipu corriger l'erreuren corrigeant à chaud leplugin RevSlider surmon serveuren tant que documentéici .

Dans revslider/includes/framework/base-admin.class.php,j'ai changé la ligne suivante (l. 21 dema version) de:

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

à:

 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

Vouspouvez utiliser «[]» au lieu de «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();

Jete dois unebière.+1et pour l'explication,en php7,vous avez des restrictionsplus strictes sur lestypes,de sorte qu'une chaîne videne peutpas avoir quelque chose ajoutétouten latraitant comme untableau.Comme @fuxia l'amentionné,`[]`fonctionne égalementbien iciet estplus 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.
