Question Enable debug mode

I'm getting the following errore while trying to add a topic;

Rendering Error in layout Topic/Edit: Unsupported operand types: string / int. Please enable debug mode for more information.


How do I "enable debug mode"?  
 

Global configuration
 
And check your settings in Kunena configuration- Uploads for Maximum Image File Size and Maximum File Size

Hello,You are trying to upload an attachment (file or image) which exceeds the limit of the settings from the Kunena configuration. It shouldn’t display an error like that but just an error message. You need too enable the debug mode into Kunena configuration, if you re-try i twill show you more details on the error. And please make a new screenshot and add into your message which helps to found the issue.

Can reproduce the error when Maximum Image File Size and/or Maximum File Size are empty.

I have enabled debug mode. Now what? Where do I look for the debug results?

What did you put in Configuration tab Uploads in fields Maximum Image File Size and/or Maximum File Size?

At the same place where you had the error message like you had showed in the screenshot of your first message

Should be this error:

Maximum File Size : 0.1 MB Maximum Image File Size :
Rendering Error in layout Topic/Edit: Unsupported operand types: string / int in .../components/com_kunena/template/aurelia/pages/topic/reply/default.php on line 44
Layout was rendered in .../components/com_kunena/template/aurelia/pages/topic/reply/default.php on line 44

@OldCharlie Please check in the configuration -> tab Uploads the value in the field Maximum Image File Size.

As requested I enabled debug mode and here is what I get:
  Error in debug mode Kunena
