Hi Ruhani. I've been using your plugin for a long time. Recently I had problem of the replies to comments appearing as new threads instead of the comments continuing in the original thread.
After checking out all plugins, I found WP Optimize is the culprit. I use WP 3.5 and WP Optimize 0.9.4
Please help. Time being, I had to deactivate your plugin.
