Xibo update to 1.8 blank screen

I have been running 1.7.4 on my web server for quite some time. Thought it was time to jump to 1.8. Followed these instructions:
Steps

You should always take a backup before upgrading your CMS Installation.

If upgrading to 1.8 series, ensure your environment meets the requirements for installation, if it does not then correct that before continuing.

  • Optionally clone your existing Xibo database and grant permissions (see Clone Database for details). It is possible to upgrade without cloning but much harder to roll back.
    
  • Backup settings.php from your installation (found in web/settings.php)
    
  • Manually take a backup of your database
    
  • Replace your existing installation with the new version from the tar.gz or zip file. Do not copy over the top.
    
  • Replace your backup settings.php file in your Xibo installation directory
    
  • Browse to http://your.server/path as normal
    
  • Log in as an administrator.
    
  • The upgrade wizard will open and show the list of upgrade steps.
    
  • Press start to run through them.
    

When I got to the step stating I needed to login as an administrator, I get a blank white screen with a url of “/install.php?step=8” in the address bar.

Any thoughts how to fix this?

Thanks

Did you follow the instruction and did not copy new installation over the top?

Could you show us a screenshot of that page please?

Yes, I deleted the old files first, then copied the new over.Not sure what you want to see in the screen shot though.

So no suggestions? I really need to get the CMS back up.
