The content access permissions need to be rebuilt. Rebuild permissions.

Hello,

After updating Organic Group module,
(there was a message “update security”)
I got a blank page

And i got the saved files to restore my site.
But The Database has been updated too and I have no backup of it.

Now I have this message :
An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. Path: /en/batch?render=overlay&id=281&op=do StatusText: OK ResponseText: Fatal error: Class name must be a valid object or a string in .../drupal-7.50/includes/common.inc on line 8026

And all my content cannot be accessed if I am not connected.

The line 8026 of common.inc is :
$controllers[$entity_type] = new $class($entity_type);

I am new on Drupal.

Thank you for yours answers, it very important

P.
