Hi all, i need support for a strange error.
I'm running the latest version of wordpress MU, when some of my users try to open a subdomain on my network, he receive a mail and a link to confirm the registration.
On click an error comes up:
An error occurred during the activation
Invalid activation key.
What should i do to fix that problem?
Please if you know something about that problem let me know, because i've made a lot of research in forums and i can't find the exact answer, you will help a lot of people having the same problem!
