Plugin breaks pelican (NoneType object has no attribute 'lower' )

[trev-dev]

Heyo

I've been trying to get this system to work for me. Every time I try to run pelican I get as far as generating the comment XML feeds and then the program breaks down and nothing else gets rendered.

At this point I am not using any of the comments in any templates. I'm simply trying to run pelican with the plugin, I keep getting NoneType object has no attribute 'lower'

I've tried both versions 1.3.0 and 1.4.0 of pelican_comment_system. I'm using Pelican 4.0.1 with pelican_comment_system and pelican installed in a Pipenv.

Here's my settings:

The only reference to the str.lower() method I can find is in the init file: https://github.com/Scheirle/pelican_comment_system/blob/0ac19ef03e81945d3ac6f58cd8ae2162f5feb9ca/pelican_comment_system/__init__.py#L182-L195

I tried wrapping the inside of the if block in a try/catch, if I do this, the script finishes, all of my site gets generated and 0 comments get generated, so the problem is definitely here. Perhaps it's in the reader_read_file() method.

I have managed to isolate my issue to Pelican 4.01. The problem does not occur in Pelican 3.71. I'm assuming some sort of breaking change occurred between 3.71 and 4.0 for the pelican_comment_system

Dug into your pull requests. Replicating this merge request fixes the plugin for me in pelican 4.0.1 - https://github.com/Scheirle/pelican_comment_system/pull/7
