Hello,

Looks like barcode library is having issue. Please check your server php error logs and let me know the error details.

If you are not sure about server error logs, you can enable app logs by changing the `log_threshold` to 1 in the `app/config/config.php` and then visit the barcode page again to reproduce errors. Lasly check the laest log file in the `app/logs/` folder.

Thank you

Thanks for the reply.
I am attaching the error log. As you can see there is now also a login problem.
I can already tell you that downloading and installing the SSM application again did not help. I did that this weekend with no success.
Thanks in advance for a solution,
Regards, Daan

Hi,
In the meantime i found the solution: changed the syntax in the file:
app\third_party\Zend\Barcode\Object\ObjectAbstract.php
line number 1201 from $text{$i} to $text[$i].
Now the barcode is correctly displayed on the print preview.
Hopefully this was the last error and everything is now working as may be expected when purchasing an application.
Regards, Daan

May I know your php version and thanks for sharing the solution

This error in log still remains during login:
ERROR - 2022-03-07 10:05:27 --> Severity: error --> Exception: array_merge(): Argument #2 must be of type array, bool given C:\POSLabel\xampp\htdocs\SSM\app\controllers\Welcome.php 36.
Thanks for the fast reply!

Hello,

This is not related to barcode and will go away as you have data. Can you please chek that line, if it is not wraped in if then do it as following

```php
$data = $this->tec_array_merge($check_ins, $check_outs);
if ($data) {
ksort($data);
}
```

Thank you

Dear,
your answer about having no data is by no means a possible cause:
- the application already has data, +6000 article lines have been loaded into it.
- the code you provided is in the Welcome.php file in exactly the same way.
- the error message:'ERROR - 2022-03-10 11:10:35 --> Severity: error --> Exception: array_merge(): Argument #2 must be of type array, bool given C:\POSLabel\xampp\ htdocs\SSM\app\controllers\Welcome.php 36'
If I type in the browser address bar after the login error this URL 'http://localhost/SSM/item.php' , everything works correctly and the user session is active.
Thanks, Daan

Hello,

By data, I mean check ins/outs. If you need, you can change the sessions settings in the `app/config/config.php`

Thank you
