  • Applies to:
  • Plesk for Windows


When logging into the Parallels Plesk Panel web interface, it shows nested windows rather than just a single window.


The issue may be caused by 'WordPressURLRewrite' ISAPI filter configured on the global level:

Start => cmd => inetmgr => web sites => right-click => properties => ISAPI filters

Here is the full information about this filter:

Name: WordPressURLRewrite
Path: C:\Program Files\SWSoft\Plesk\Additional\Wordpress\rewritev11\WordPressURLRewrite32.dll


Remove the filter on the global level and restart IIS. The issue should disappear.
If one or more of your sites require this filter to function correctly, please enable them on the domain level.
