Hello, we have a custom theme . I have the error that say layout.noscript.warning.php is missing . Copying the file from core/templates is okay . Any problem for do that ?
try to use
<?php include(OC::$SERVERROOT . '/core/templates/layout.noscript.warning.php'); ?>
That will pull in the template from core
In terms of encapsulation of the code the script should simply be copied over to the new theme (and adopted if necessary)
