Drupal 8.x

I have installed drupal and solr along with Search API and Solr Search Modules and can create a Search api sever that connects to my solr core. But i am unable to search the indexed data on that solr core. How do i search the content already on the solr core?

Hi.
I am creating a rule in drupal 8 with the event: "After saving a new comment"
I add a condition: "Condition: Node is of type".
 > Values:
    Node value selection: @node.node_route_context:node
    Content type value: page
I clean cache.
I received an error with the following message in my log of errors:

TypeError: argument 1 passed to Drupal\rules\Plugin\Condition\EntityIsOfType::doEvaluate() must implement the Drupal interface \Core\Entity\EntityInterface, string given in Drupal\rules\Plugin\Condition\EntityIsOfType->doEvaluate()

Hi all,

First I am sorry, as I know this has been asked several times. I wish to remove some , not all some media icons [ SMI ] from top of website. These SMI came pre-installed with theme. I've read a few posts on-line from people asking the same question, but I can't seem to work it out. The other solutions I read them tailored to the user's specific theme they used.

Thanks
