I've installed the Social Bookmarks and AJAX Edit Comments plugins into my blog. I've tested the AJAX Edit Comments results on several browsers/computers, and the plugin works fine. The Social Bookmarks plugin shows icons with live links, but no AJAX effects, even when chosen via admin. The fact that AJAX Edit Comments functions as it should tells me that that the AJAX function is present, and "communicating" with admin configs. I've reinstalled Social Bookmarks to no avail. What should I investigate?
