Dude I know exactly what you’re going through I was averaging 700 hits a day and then last week they were staying at a pretty even 850 with 880 being the high. Then two days ago I noticed my theme looked a little funny, so rather then jumping in to fix the code my gf said I just find a new one something more suited for my site and personality. So I activated a theme I had previously installed. The next day I jumped on and noticed I didn’t get a single hit, I got several comments but the stats said 0 visitors. So it’s gotta be a plug in problem. https://www.mysterchr.com if you wanna check it out.
