Unexpected Website Error

Hi, My website at www.mindsets.eu appeared to crash after some configuration updates, so I restored to the latest back-up using shared hosts softaculous application. Despite attempts at restoring from both the two latest back-ups, I keep getting the same error message, i.e.: "The website encountered an unexpected error. Please try again later." The last lines in the error log are: [15-Feb-2019 13:05:43 Europe/Helsinki] Uncaught PHP Exception Drupal\Core\Extension\Exception\UnknownExtensionException: "The module opigno_lms does not exist." at /home/liikanjitsu/public_html/mindsets.eu/pedles/web/core/lib/Drupal/Core/Extension/ExtensionList.php line 257 [25-Feb-2019 13:48:12 Europe/Helsinki] Uncaught PHP Exception Drupal\Component\Plugin\Exception\PluginNotFoundException: "The "" entity type does not exist." at /home/liikanjitsu/public_html/mindsets.eu/pedles/web/core/lib/Drupal/Core/Entity/EntityTypeManager.php line 133 The code at the line 133 region consists of: elseif (!$exception_on_invalid) { return NULL; } throw new PluginNotFoundException($entity_type_id, sprintf('The "%s" entity type does not exist.', $entity_type_id)); } /** * {@inheritdoc} */ I have no idea what it is on about or even if it is relevant to the current problem. Can you help me resolve this error message please?
