Comments off, despite being on

Hey all,
this is a topic covered extensively, I’ve read at least 10 of them, but none of them solved it for me.

I have comments on. Yet under my posts it say comments are off. I’m using a theme I bought 4 days ago and am new to wordpress (yes, I’m self hosting) I recently moved from Blogger and imported site.

From what I gather it must be something overriding my overall post setting on individual posts.

Under Settings>discussion I have this ticked on: Allow people to post comments on new articles

Under Appearence>Editor – Comments (comment php) I see this which I guess is the culprit. Should I edit this in some way?

Another issue is that on the script page where I bought it from the developer has this written on one of the pages under an example of a comment section:

You may use these HTML tags and attributes:
<a href="" title=""> <abbr title=""> <acronym title=""> <b> <blockquote cite=""> <cite> <code> <del datetime=""> <em> <i> <q cite=""> <strike> <strong>

Is that what I should past into the php code somewhere?

He is not however interested in helping me, that’s why I post here. Has anyone experienced and solved this problem?
