Just wanted to give you an update. I reverted back to Kuroi's 1.4.7 version on both these sites. One of them now works like a charm. the other still has the same issue.

Here's a list of the mods also incorporated into the problem site. If you are aware of any conflict, I would really appreciate a head's up.
