This is not a common problem or not reported any user before. So, we believe that it is a issue of your site specifically. We need to check your WordPress Dashboard to find out the issue. If that is Theme Related, we must resolve the issue. Please provide Your Site URL, One Temporary Admin ID and Password to our E-Mail [email protected] when your site will be online. You can install the site in live domain activating the Maintenance Mode or can install in a sub domain or sub folder. Thus your visitor will not find the development site.
