3371145 - Sites are not accessible post refresh


After the instance refresh, sites become inaccessible due to the reception of an application error.

  • Error message= Request processing failed; nested exception is java.lang.NullPointerException: Cannot invoke "com.plateausystems.elms.framework.coverpage.api.CoverPageDataVOX.getLayout()" because "coverPageDataVOX" is null

Reproducing the Issue

  1. Access the site using the URL
  2. Application error occurs


When LPA manual refresh is done, the data from certain tables like pa_cover_page_custom_tile and pa_home_custom_tile is inadvertently deleted, resulting in null pointer exceptions being thrown by external sites.


After a manual refresh occurs, the custom tiles associated to the site will need to be recreated as the default external login page will only be displayed.
