Hi?@sergiourra, thank you for reaching out.
Can you please confirm if you’ve entered a valid license or gone through the process to get a new license after installing the plugin on the site? You will need to enter a license after installation to complete the setup.
Usually, the yellow “Wordfence installation is incomplete” bar indicates that you haven’t installed a new or existing license or that the admin email address has been removed from the Wordfence settings.
If you’re seeing this error when a license key is installed, please click the “Resume Installation” button while keeping a Browser Console open to see if you can detect any JavaScript errors or files that fail to load. If you see any red text in the console, please take a screenshot and send it to me.
Thanks,
Mark.
