About one year ago, I started my blog: Paretje's blog.
And now, I wanted to test the trackback and pingpack functions on my blog. I installed a test blog, and tested it.
My blog sends perfectly pingbacks and trackbacks, but when I try the same with my test blog, only the trackback has effect.
I tested if there was maybe a bug in my design, and so I tried it with the default one: no effect.
Then, I've tried it by reuploading ALL the WordPress files on both blogs: no effect.
So, I'm curious what it can be the problem.
PS: both blogs run on the same server ;)
