I have done all the instructions from https://www.flinkiso.com/manual/installation.html, but the problem still appears like this. An internal error has occurred.

Possible causes:
The database is not connected.
Make sure you have imported app/webroot/schema/flinkiso-on-premise.sql
Make sure to add the database configuration in app/Config/Database.php under the default configuration.
Directory permissions are incorrect
The following folders must have read-write-execute (recursive) permissions
app/webtoot
app/tmp
lib/Cookie/Cache
The table does not exist or the model is incorrect.
If this error occurs during installation, visit: https://www.flinkiso.com/manual/installation.html and follow the installation instructions.

You can also use the FlinkISO Forum : https://forum.flinkiso.com/ for possible solutions.

If you have successfully installed the application and an error occurs after creating a custom HTML form, this error can be resolved by recreating the form.

If this error appears after creating a child form or a form linked to a child document, recreate the parent form.

Additional Info: Remove "STRICT_TRANS_TABLES" for sql_mode from MySQL configuration file.

Note: I have also removed "STRICT_TRANS_TABLES" for sql_mode from the MySQL configuration file.

Hi HENGKI,

You need to check your app/tmp/error.log file to check the error details and share with us.

Hi Aditya,

There could be multiple reasons this error may occur.

1. File you want to download, does not exists
2. ONLYOFFICE & FlinkISO servers are unable to communicate with each other
3. You may not have wkhtmltopdf or pdfTK installed.
4. wkhtmltopdf is not generating a required files
