problem with database upgrade

[gayelston]

When you are doing your upgrade steps, do each suggested version one-step-at-a-time, manually unchecking the extra steps before proceeding.

If uncertain about a step, click the ReCheck button at the bottom to get a refresh of the screen.

Hi,
I installed a new shop, v1.3.8a, checked it was working ok (login etc) then followed the instructions for backing up & restoring a database, here:https://www.zen-cart.com/tutorials/i...hp?article=103
I followed them step by step because I've been trying to get this to work for nearly 24hrs!.
The database I was importing is a v1.3.0.2 so I followed the database upgrades single steps at a time.
All finished so I set the config permissions, change the zc_install name & click go to admin.
I try to log in & the screen just goes on a loop, no error messages just back to the screen.
My server has both php4 & 5 running, phpMyAdmin - 2.11.1 & MySQL client version: 4.1.22.
I've tried to find an answer that fits my problem on the forum etc, but this problem is usually for earlier versions of Zen Cart & not for v1.3.8a.
Really don't know what to do next.
Can anyone help please?
This is all on a practise site, & I'm VERY relieved about that!
Thanks in advance.
Regards
