1.5.6 upgrade 2.3 Could not load config default! [solved]

Hello,
I have copied my database to a new database, using a secondary copy of my web server files, went through the upgrade process for 2.3.x
that finally completed successfully and receive the following error on the main page now:
Notice: Error: Could not load config default! in /var/www/html/system/library/config.php on line 27

using mysqli with php 7.0
centos 7
I installed these modules on the new server - maybe I missed one:
php70u-mcrypt.x86_64
php70u-xml.x86_64
php70u-mbstring.x86_64
php70u-gd
php70u-json

Any suggestions...

This was caused by some spurious data in my config definition in root config.php
define('DIR_CONFIG'.........

on to the next error.

Just wanted to put this out - maybe help someone else:
error message:
PHP Parse error: syntax error, unexpected ')' in /var/www/html/system/helper/json.php(126)

I was receiving this error message since I did not have json module installed in apache/php
yum install php70u-json
restart apache
solved the problem

Glad you got it working and well done for posting up the solution to your problem.
May help someone else in the future if they come across the same error.

Also if you edit your first post and add [SOLVED] to the title it is much easier to search for solved posts
