Blank admin login page - PHP Fatal error: Call to undefined function zen_get_ip_addr

[batta]

I am upgrading from 1.3.9 to 1.5.4 (attempting to do it by the official Zen Cart method). After running zc_install when I attempted to log in to the admin area I got a blank screen. No error messages, nothing.

Checking the mydebug log I found

PHP Fatal error:  Call to undefined function zen_get_ip_address() in /xxxxxxxxxxxxx[admin]/includes/init_includes/init_sessions.php on line 34

Lines 30-37 of admin /includes/init_includes/init_sessions.php read as follows:

/**
 * tidy up $_SERVER['REMOTE_ADDR'] before we use it anywhere else
 */
$ipAddressArray = explode(',', zen_get_ip_address());
$ipAddress = (sizeof($ipAddressArray) > 0) ? $ipAddressArray[0] : '';
$_SERVER['REMOTE_ADDR'] = $ipAddress; 

It is $ipAddressArray = explode(',', zen_get_ip_address()); which appears at line 34. When I comment out that line I am able to access my admin area and doing that has not led to any apparent problems, but since I do not understand the intent of that line and have not tried to go live I worry about unforeseen consequences. Can anyone tell me what problems may arise from commenting out that line and what I should do to fix it?

If relevant, PHP shows as version 5.4.45 and MySQL as version 5.5.45.

Thank you.

Apparently you haven't upgraded your /admin/includes/functions/general.php ... which is where that function is defined.

Or, you've replaced the new one with an old one when installing a plugin for an older version, instead of merging the changes into it.

Exactly right, Stock by Attributes caused my problem, and I now realized that the latest version of that is reported to be incompatible with ZC 1.5.4. I think I am under control now, and appreciate the information.

Latest version of SBA is available from https://github.com/mc12345678/Stock_...butes_Combined and *is* compatible with ZC 1.5.4.
