Hello

After an upgrade to xwiki 15.10.13 I can’t access the admin panel anymore there is a velocity error

We use a custom skin but it’s the default XWiki.AdminSheet from 15.10.13 admin extension

org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [#if ($request.xaction == 'switchContext')
  $response.sendRedirect($request.target)
  #stop
#end
...

  #end
#end]

So I was checking line 63 for java.lang.NullPointerException at xwiki:XWiki.AdminSheet[line 63, column 31]

but I don’t see anything relevent there

Do you have any information that can help please ?

Regards

This is how it looks

Is there anyway to completely restore the administrator-component from the server ( config or anything ) ?

  #set ($whereClause = [])
  #set ($discard = $whereClause.addAll($whereClauseWithoutGlobal))

after editing the file to check notNull and finally rollback the whole file it works. Maybe there was some wrong cache on the server
