Hello, 
There is an issue when a user is posting comments using the default commenting tool of easyblog. The error occurs when user clicks on one of the two list buttons from the toolbar. 
Searching the files, I could easily fix it updating the files 
- components\com_easyblog\themes\wireframe\comments\bbcode.js
  - components\com_easyblog\themes\wireframe\comments\default.js
  - administrator\components\com_easyblog\themes\default\comments\form.js
  
 
Each of these files containent \\n instead of the \n for the two list element of the EasyBlogBBCodeSettings objects.
Updating these solved the issue I had. 
Regards.
