After attempting to update to version 8.1.5 I received the
- "The website encountered an unexpected error. Please try again later."
error on many pages. I also get the following error in Recent Log Messages;
- "Drupal\Component\Plugin\Exception\PluginNotFoundException: The "2" plugin does not exist. in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 52 of /home/username/public_html/domain/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php).
Any ideas what could be causing this or how to fix it?
I just tried once again to update from 8.1.3 to 8.1.7 and am getting the same errors. My 8.1.3 site was stable with no errors.
Specifically, the site has the following issues after updating and after running update.php several times.
- non-admin users can't log in; they receive the white screen of death upon login attempt, and can't even navigate to a different page than the default user page. The can only successfully logout using /user/logout to get back to the working frontpage and other working content pages.
- when logged in as admin, eveything seems to work except for the "extend" and "people" admin tabs, which result in a wsod.
The reports details show the following information after an unsuccessful attempt to access;
