Hello,

Please check your server php error logs and let me know the details so that I can suggest.

You can try to enable app logs by changing the `log_threshold` to 1 in `app/config/config.php` and the visit the page again to produce error. Lastly check latest error logs file in the `app/logs/` folder.

Thank you

any clue?

Hello,

Do you have the [iconv library](https://www.php.net/manual/en/iconv.installation.php) installed on your server?

_If no then please install it._

1. Please try to download the latest file and then replace the `vendor` folder with latest.

2. Please edit the `app/config/config.php` and look around line no 134. The `composer_autoload` should look as follwoing

```php
$config['composer_autoload'] = FCPATH . 'vendor/autoload.php';
```

If not as above then you can change the line and try again.

Please try above suggestions and let me know the results.

Thank you

Hello,

Please check with your server admin about iconv library.

Thank you
