I'm trying to get a new contributor for my blog, but for some reason, every time I try, I run into the same problem/error.
After the invite is sent out, and followed through the e-mail it says "Whoops, you can't use an activation key you've created for someone else." I've tried this on multiple e-mails and get the same results. I cant seem to get around this nor find much information why this is happening. Any idea's? Thank you all very much in advance.
The blog I need help with is chemengineeringposts.wordpress.com.
