I've been having a problem with my WordPress site (www.keyofgrey.com) since yesterday. I posted yesterday, and the post was taking a minute to load while any other post took seconds. The post itself had a picture at the top, and a Youtube video embedded at the bottom. I removed both independently of each other, updated the post, and the problem persisted.
I proceeded to delete the post and rebuild it with the same picture which also didn't work. I then deleted the post and used a completely different picture, being careful to delete all traces of the original picture from the gallery and webhost (Dreamhost). Today, the problem still persists, so I put up a completely new post without any photos, only a thumbnail for the front page through the "excerpt" field, as is standard with the theme I'm using. I'm still experiencing the same speed issue as with my previous posts.
I have not changed any plugins, or anything else in my WordPress settings and I'm at a loss as to the problem. I've posted everyday for almost a year, and it may break my streak. Any help would be much appreciated.
