Hi @hilabs, sorry to see you’re having problems with this and apologies for the delay over the holiday and New Year period, which I’m doing my best to get back up-to-speed with.
We have seen possible issues installing keys automatically more than 24 hours after generation. Additionally, if you are in a different browser than the one used when requesting your Free Wordfence license, you will be unable to automatically install it. In those cases you will need to manually copy and paste the key from the email to complete the activation of Wordfence Security.
Aside from verifying that you did not inadvertently copy only part of the license key, I would check whether you can install the license when Wordfence is the only active plugin on your site. There could be a Javascript conflict with another plugin potentially stopping the code executing the verification check.
Let me know if it still doesn’t work after trying those things. Our forum guidelines do require one topic to cover the issues for one user, so if anybody else has tried all of the above steps with no luck and haven’t already, please start up a new forum topic and we’ll be able to look into your site(s) on an individual basis.
Thanks,
Peter.
