- Don't use embedded comment form,
- Disable per-post comment feeds in your blog, or
- Edit template html.
The easiest way is to change embedded comment form to popup or full page, or disable per-post comment feeds in your blog settings. But if you want embedded comment form and post comment feeds enabled, then you need to edit template. Note: these instructions do not apply to dynamic views.
For the template editing option, this has worked for me:
Open template for editing, and click "Expand Widget Templates". Find this block of code, which is there twice (for mobile and normal viewing), you can search for <b:if cond='data:post.showThreadedComments'>:
<b:if cond='data:blog.pageType == "static_page"'>
<b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/>
<b:include data='post' name='comments'/>
</b:if>
</b:if>
<b:if cond='data:blog.pageType == "item"'>
<b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/>
<b:include data='post' name='comments'/>
</b:if>
</b:if>
Change both the blocks to this:
<b:if cond='data:blog.pageType == "static_page"'>
<!-- <b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/> -->
<b:include data='post' name='comments'/>
<!-- </b:if> -->
</b:if>
<b:if cond='data:blog.pageType == "item"'>
<!-- <b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/> -->
<b:include data='post' name='comments'/>
<!-- </b:if> -->
</b:if>
I.e. comment out the if-elses where "threaded_comments" are included, and include only "comments". Remember to do this twice, for both blocks of same code. To avoid extra javascript loading, search this line:
<b:include data='post' name='threaded_comment_js'/>
and change to:
<!-- <b:include data='post' name='threaded_comment_js'/> -->
Save template. Now you should have the "good old" comments back with embedded comment form, and any modifications and hacks that were made to comments system.
