I have emailed you a few days ago via your contact forms and again today but got no response so far.
I am having problems using your forums, my posts never appear!
Thanks for looking into this issue.
BTW. the problem I am emailing you about is described in this thread but your solution doesn't help me solve the very same problem: https://www.wordfence.com/forums/topic/wordfence-api-error-key-already-used/
