Comment not respecting line breaks (Drupal 7) All of my comments for all of my content types do not respect show line breaks.  I have tried to dig pretty deep into this issue but I now feel quite stuck.  

This is what I discovered.


The problem is not related to the text formats. (I have verified that Convert line breaks into HTML is checked.)
The problem may have to do with safe_value. I used dsm() to show content of the $vars variable inside the hook_preprocess_field() implementation of the theme, which shows the value of the comment body has line breaks, but save_value doesn't.
The issue is not related to the format. With dsm() I have verified that the comment body is using  the Filtered HTML input format, which I believe is correct. 


This is what dsm() outputs for the comment body.
When I found this problem it was because the results of the filter were being stripped by another filter.

Go to /admin/config/content/formats and check your filter processing order. The 'Convert line breaks into HTML' should be the last one.
