Error trying to Log Into Admin: Call to undefined function

I used winmerge to maintain my text modifications to english.php, etc but had no modifications to function files.
Used zc-install to update my config files and database
After upgrade, I renamed the admin folder to sales_info and updated the config file
Site works fine but cannot log into admin
The Debug file shows: PHP Fatal error: Call to undefined function zen_validate_user_login() in /home1/xxx/xxx/xxx/sales_info/login.php on line 38
I've checked the entire download file and this function does not exist.

Help!

With a 1.5 install you shouldn't have to edit the configure.php files to change the name of the admin directory. At least that's the way it is with a new install, not sure with an upgrade. Perhaps when editing the file you inadvertently created a coding error.

The function should be declared in your sales_info/includes/functions/admin_access.php file.

My bad, found that the admin_access file had not been uploaded.

I'm having the exact same problem and the debug file is giving me a similar error:

PHP Fatal error: Call to undefined function zen_validate_user_login() in /home/digicig/public_html/zc_admin/login.php on line 38

I have an "admin_access.php" file in the zc_admin/includes/functions directory.

Am I missing something here?

TIA

Could you check that you have the file:
/yoursecretadmin/includes/auto_loaders/config.core.php

And open it up and search for:
admin_access.php

You should find it 3 times ...

NOTE: you will later want to change the name of your /admin directory as you told everyone your secret admin directory name ...

Thanks Ajeh,

Yes, admin_access.php appears 3 times in /yoursecretadmin/includes/auto_loaders/config.core.php

Evidently you're missing files from your server.

Thanks Dr,

I've re uploaded all the files again and still no joy :(

What does the new error say?

There is no error message. The animated progress image spins around then the login page just reloads.

However, If I purposely enter a wrong username or password it gives me an error message.

So, your symptoms are completely different from the original topic of this thread?

No, my symptoms are the same:

Site works fine but cannot log into admin
The Debug file shows: PHP Fatal error: Call to undefined function zen_validate_user_login() in /home1/xxx/xxx/xxx/sales_info/login.php on line 38

Okay, then, as said previously, you're missing the file that contains that function, or you've got other files installed that are preventing that file from loading normally.
So, it comes down to:

• you have a bad FTP program which can't properly upload files
• you have changed core files, and broken normal operation
• you have installed addons, or have leftover addon fragments, which are interfering with normal file loading activity
