 * I am running this on WP Multisite and getting following error when selecting ‘
   Excludes’ option for file backup:
    — Warning: uasort() expects parameter 2 to
   be a valid callback, no array or string given in /siteroot/wp-content/plugins/
   backupwordpress/vendor/symfony/finder/Finder.php on line 768
 * Catchable fatal error: Argument 1 passed to Symfony\Component\Finder\Shell\Command::
   setErrorHandler() must be an instance of Closure, null given, called in /siteroot/
   wp-content/plugins/backupwordpress/vendor/symfony/finder/Adapter/AbstractFindAdapter.
   php on line 99 and defined in /siteroot/wp-content/plugins/backupwordpress/vendor/
   symfony/finder/Shell/Command.php on line 225

    Tried to debug the issue but could not find what is causing this problem.
 * Any help is highly appreciated.

 * Sorry to hear that. I just tried on a multisite test site I have, but couldn’t
   reproduce the issue.
    Could you provide as much detail as possible regarding 
   your server configuration / software versions,…
 * thanks
