Hi @rgi001, Thank you for reaching out to us.
This sounds pretty uncommon, so I’d suggest clearing cache (site plugins and local browser) and disabling all other plugins except for Wordfence, then trying again to see if there’s a plugin or theme conflict causing the issue. You could also revert to a default theme, such as Twenty Twenty-Three.
If it works as expected, then reenable your plugins and theme one by one until the issue recurs to help find the cause.
If there’s a plugin or theme conflict, I would suggest changing the Wordfence Web Application Firewall into Learning Mode. From the Wordfence Dashboard, click on Manage WAF. Then you will see Basic Firewall Options > Web Application Firewall Status. Change the option to Learning Mode. Now confirm that you can view the Login Security Page. Once done, switch the WAF from Learning Mode back to Enabled and Protecting and test to see that you can still view the Login Security page.
https://www.wordfence.com/help/firewall/learning-mode/ is an amazing resource for learning more about the WAF and learning mode.
Let me know how it goes.
Thanks,
Mark.
