Drupal 8.x

I wanted to get some feedback on whether Drupal 8 would be feasible for this SaaS project. I am mostly concerned with speed and scalability, with the potential of using it as a backend to a progressive web app, perhaps with Contenta. Ultimately this would need to be able to operate as a SaaS where each instance of a content type is charged a recurring monthly fee.

Is there any modules which can be used to collect visitor information such as IP address etc.

We have someone leaving abuse on our comment for and sooner then stop people commenting we want to be able to ban the ip address range and see if we can identify the person.

We have tried to use Visitor but it breaks the site so anything even if it is an external solution which can be integrated into drupal (8) would be good.

We have put live chat on so we can see who comes and goes and what pages are viewed.

Thanks in advance

Hi,

I have updated my website from Drupal 8.3.7 to 8.4.8 and updated the Lightning to 2.2.0. Lightning 2.2.0 removes Page Manager which was previously bundled with Lightning; so I have to install Page Manager manually.

Now, I am trying to install Page Manager 4.0-beta2 but getting the error:

PHP Exception Drupal\Component\Plugin\Exception\PluginNotFoundException: "The "onecol" plugin does not exist." at .../docroot/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php line 52

Any help would be appreciated.
