I use Shapely on my blog (http://lebeauleblog.com) and I have noticed some irregularities with comments. Some readers mentioned that it takes longer to comment now that I have switched to the Shapely theme. Usually I comment through the WP dashboard, so I had not noticed. But today I tried to post a comment on a post and it never did show up. Every time I tried to post the comment, a little wheel spun for a couple of seconds and then the comment and the box just disappeared.
Please let me know if you need any additional info. Thanks for your help.
