Error upgrading from 1.6 to 1.7


I was trying to upgrade from 1.6 to 1.7. After uploading 1.7 files, when I go to homepage, it says website has redirect loop.

But i successfully upgraded to 1.6.3.

Tried clearing cache and session but lo luck.

Are you using the CMS as a super admin user? It might be that it is trying to show you the upgrade page, but you don’t have permission to use it (or something like that)

Yes I am trying with super admin only.

I had no problem upgrading to 1.6.3

1.6.3 and 1.7 have a slightly different upgrade mechanism, so there may well be some differences between the two. Was your 1.6.3 a standard installation (no tweaks?).

I’m not sure why you would be having trouble when others aren’t

I’m struggling with the exact same issue. Going from version 1.6.4 to 1.7.3.

  • Removed all previous 1.6.4 files
  • Placed the 1.7.3 files
  • Copied the backup settings.php from 1.6.4 to 1.7.3.

Opening the webpage resulting in a loop error (Do not know the exact English error. Using a Dutch web browser.)


When removing the settings.php file, and refreshing the page, the Install page opens.


I used a custom made Theme. Setting the theme back to ‘default’ first, then placing the new files, the Upgrade page shows !!
