Select content button doesn't work

Hello,

I added the code mentioned here https://help.forumotion.com/t93456-select-content-button to my website but it doesn't work.

Also I want the code to be on the left not on the right because my forum in Arabic, the code starts from the right side and I want to fix it.

Forum version: ModernBB
Browser: Firefox

Do you have JavaScript Management on?

The topic was posted in the wrong section, so I have moved it to the correct section. Please read our forum rules:  ESF General Rules

This tutorial is compatible for all forum versions but not for ModernBB and AwesomeBB if I recall correctly

Yes Javascript code management is active. No other code for ModernBB?

Is there a css code to change the direction of the text inside code block?

Thanks. The text direction solved using the CSS code below

Code:

dl.codebox code { 
   direction: ltr;
}
