Doesn't Work With Customized Comments Template

Unfortunately the plugin doesn’t work if certain simple customizations have been made to the comments template. I opened a support thread two weeks ago but got no response from the author: https://wordpress.org/support/topic/broken-html-on-posts.

In my case, the customizations were made before the plugin was installed, so I can’t comment on how the plugin works without these customizations.

Since one of the main purposes of Cache Buddy is to affect the behaviour of cookies for commenters, I would expect the plugin to work despite a bit of custom code in the comments template.
