Creating view using Index results in "plugin does not exist" I was having some problems with Search API after adding my second index (using DB not Solr).  The index I was trying to create was supposed to just be the body and title of a content type.  I was able to build the index just fine, but when trying to attach it to a view (My Test View) I'm getting a funky message directly above the Preview section on the view page.  


  The &quot;views_page:my_test_view__page_1&quot; plugin does not exist.


I am utterly confused by this.  I uninstalled Search API and reinstalled, but the only change is this now happens to both views using a search index.  I am able to successfully create non-search index views, but that's the only evidence I have this is even Search API's problem.  Can someone please direct me on how to start debugging this?  

This is Drupal 8.
I now believe this is some type of caching issue, though I'm not sure why.  Originally I thought uninstalling a particular module fixed the issue, but the "plugin does not exist" error appeared the next day when creating a new view. Clearing the cache seems to clear the error, which is a good enough workaround for now until I have more time to dedicate to this.
