I was wondering last night why there hadn’t been any comments about the launch of our new design or the release of the evolution theme, particularly as traffic has been high the last few days. I was busy tweaking the design yesterday so I didn’t have too much time to look into why but thankfully Mani from Daily SEO Blog to tell me that he couldn’t leave a comment and I found the problem right away.
Turns out the math comment spam protection plugin was still activated but the field had been removed from the comments.php file at one point. This resulted in an error of no spam protection being completed even though you didn’t ask for it, frustrating to say the least.
I like the math comment plugin however I’ve found out that if someone does forget to complete the spam field and then clicks back on their browser, their comment is not saved and they have to type it all again. This happened to me on another site and it was incredibly annoying so I have removed it for now (until I find a better plugin).
Once again, apologies for comments being broken the last few days. We had tested comments the day before and it seemed fine so I didn’t think that could be a problem.
Thanks again to Mani for pointing this out to me 
I feel your pain.
My joy recently was neglecting to add the website tracker code when I updated my blog look and feel. So *that's* why supposedly no new visitors showed up!
Glad you got it figured out,

Good, I also sent you an email. But having problems with my Internet and it might not have come trough. Glad you got it sorted.
I highly recommend WP Spam-Free
no annoying captcha
I always copy my comment before submitting unless I use Opera.
Thanks for the tip Se7en
Just realized I already have that plugin, I deactivated it before for some reason (I just can’t remember why now!
