Admin directory error after update to 2.3.1 from 2.3

[brightboss]

After I updated to 2.3.1 I get the following code error. As a temp fix I manually typed in admin in header.php - But I should have to manually fix this. What is it that's going wrong that it's not detecting the admin folder? Here is the code error. Any help would be much appreciated. Thanks.

Code of Error:

Code: Select all

Warning: include(/home/viewgo/public_html/_ADMIN_FOLDER/functions.php): failed to open stream: No such file or directory in /home/viewgo/public_html/admin/header.php on line 21

Warning: include(): Failed opening '/home/viewgo/public_html/_ADMIN_FOLDER/functions.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/viewgo/public_html/admin/header.php on line 21

Fatal error: Call to undefined function get_true_max_filesize() in /home/viewgo/public_html/admin/header.php on line 82

I found the fix. I noticed that my config.php file did not have this line "define('_ADMIN_FOLDER', 'admin');", after comparing config-sample.php

Code: Select all

define('_ADMIN_FOLDER', 'admin');

Thus the reason for it working when I manually stated the path in header.php
