'ARTICLE NOT FOUND' message appears in header of all knowledge base articles

After upgrading to Dublin or Eureka from a previous release, article titles do not appear within the header of all the knowledge base articles.

1. Log in to Hi.
2. Navigate to Knowledge Base > View.
3. Select any KB article.
   Note that "ARTICLE NOT FOUND" appears in the header of the KB article.

- The UI Page kb_view needs to be removed and replaced with the new version (attached xml file) by a system administrator:

/nav_to.do?uri=sys_ui_page.do?sys_id=1f5e464b0a0a0b3200dbbe75f65063e4

- If the Import XML fails for an Admin user, most likely the pre-existing UI Page (OOB sys_id = '1f5e464b0a0a0b3200dbbe75f65063e4') has not been successfully removed and the logs will show a unique primary key violation error.

- The Script Include KnowledgeHelp should also be reverted to the OOB version:

/sys_script_include.do?sys_id=e038f4680a25810400e525225ade92a0

- The UI Macro kb_stripe_text can be modified to comment out the sections evaluating the article for validity.
