Notice: unserialize(): Error at offset 0 of 5 bytes in index.php on line 37

I upgraded to opencart 2.03.1. I am getting unserialized() error at offset 0 to t in index.php. I found the line of code. It is the following:
foreach ($query->rows as $setting) {
if (!$setting['serialized']) {
$config->set($setting['key'], $setting['value']);
} else {
$config->set($setting['key'], unserialize($setting['value'])); <=== error is on this line

So I changed that line to this to see the output: $config->set($setting['key'], unserialize($setting['value'])); if (!unserialize($setting['value'])) echo $setting['key']."==>".$setting['value']."<hr>";

I get these 2 errors:
Notice: unserialize(): Error at offset 0 of 5 bytes in C:\xampp\htdocs\store\admin\index.php on line 39
config_complete_status==>["5"]

Notice: unserialize(): Error at offset 0 of 5 bytes in C:\xampp\htdocs\store\admin\index.php on line 39
config_processing_status==>["2"]

I started with a fresh database so these are values put in by the install. Does those errors mean that the value should be serialized or no?

I have attached what those entries look like in the database.

That's not serialized data it looks more like JSON encoded. JSON is used in later versions of OpenCart. It looks like you have got something mixed up somewhere.

What versions are you upgrading from and to?

The current version is 1.4.9. I was trying to get it to 2.3.X before going to the latest version. I read that 2.X doesn't use serialize but JSON but I haven't been able to find how I upgrade my 1.4.9 to that.

2.1.0.0 was the first version to use JSON for the settings. It sounds like you have already run the updater of a later version, but your index.php is from 2.0.3.1 or earlier.

I will try to get 2.3 to work but I thought I was seeing the same code in the index..php
