Shop details will not save - forces login page. Admin directory missing

[rkenley]

Hi, thank you for responding.

There are no log files in the site log.

And the problem is that everything seems to be normal, yet I can't administer the site. I can login as admin and get to the My Store configuration page. I am familiar with this page. But selecting any item on this form, or trying to save store details on the initiation form, all fail. As soon as I save or select a menu item, the system immediately jumps back to the admin login form. I can't get beyond this.

This is my second go at doing this - I tried it with 1.5.67a 2 years ago and I now remember I got the same result and could not find a solution.

I have checked all the permissions I am supposed to set and they are correct. I tried a reinstall but this made no difference.

If its relevant, I unpacked 1.5.7 locally, uploaded it to the site and ran the installer via the web. I have done this several times in earlier years with earlier versions and never had this problem.

I am thinking I must have a setting incorrect????

OK, I have found my post from 2 years ago and at that time I found that 1.5.7 does not like PHP 7.1 - it works if I change to 7.3... however I NEED to stay with 7.1. Am I going to have to abandon ZenCart? Or maybe change to 7.4 to edit the site and then change back? I will try that now. But it seems clumsy.
