Hi @farhannaseem,
As your screenshot shows a server forbidden page rather than a Wordfence-branded blocking page, it looks like a potential permissions issue or some other kind of access problem to your site at first look.
If you do have Wordfence installed, you could try:
- Please use FTP/SFTP — or any file manager your web host provides via their administration panel.
- Look inside the /wp-content/plugins/ directory and rename the wordfence directory to wordfence.bak.
- Once you have logged in to your WordPress admin you can name the folder back to wordfence again.
- Refresh your dashboard and you should be able to see Wordfence Active again. If not, go to the Plugins page and Activate it.
However, after renaming the Wordfence directory, if this issue persists you may need to get in contact with your host to see if they can work out why your site is returning this response.
Thanks,
Peter.
