404 error

Hi @dimath99,

This is probably caused by a Firewall or security setting or plugin. Could you try to temporarily deactivate your Firewall plugin to check if this solves the issue?

We have written an article about a related subject with All in one WP Security:

Please let us know if this solves your problem.

Kind regards,
Leon
