Drupal 8.x

I need to target an inline entity form submit button with jquery. The button I'm targeting is dynamically generated. I have the type and class name I need yet the code does not work. I am able to target the submit button for the node so I know the code I have works on some level. I've included the code I'm using below. Any help would be appreciated.

I am running a Drupal 8 multisite. All was well until I used Drush to update to the latest version and got a bootstrapping error.  

This is the latest error:

Hi there

I'm setting up a website with drupal 8 on an Amazon server.
I'm having trouble creating a REST api from a content type that references another content type (or even a taxonomy). When I access the authenticated REST in drupal, all referencies fields are shown, but when I am not authenticated, the referencis fields are not shown.

for example:

authenticated

On a new site I just enabled the core actions module and when visiting its configuration page the site breaks (white screen) "The website encountered an unexpected error. Please try again later." message.

It's not a fresh install, but has very minimal work done on it.  I added paragraph field to the basic page nodes, created an event node type and a view, configured the contact form, edited the main nav and configured it with ultimenu, and added a bootstrap subtheme.  No custom modules.

      I am working in an IP test lab.  I am doing some testing with some equipment and I need a Webserver to simulate Internet traffic on my network in the lab. 

      I installed WAMP on a Windows 7 laptop.  Then I copied all of the current Drupal files into the /www directory. 

      Every time I would try to run the Drupal installation, it would crash.  I tried it with both Drupal 7 and Drupal 8.   In both cases, the installation always crashes before I complete it.
