    Scan Engine Error: The signature on the request to start a scan is invalid. Please try again.

    Hi @umik,

    We’ve noticed a recent possible incompatibility with “Change wp-admin login (change-wp-admin-login) – Version 1.1.7” that causes this error message to appear on some other customer sites. Can I confirm whether you have this plugin installed and if so, does disabling it cause the scans to resume without the signature error?

    Thanks,
    Peter.

    Hello

    Thanks for your answer. I am using Change wp-admin login.

    I can confirm that if i disable the change wp-admin login, the scan works immediatly.

    I should ve thought of disabling the other plugins for troubleshooting.

    For information. Is it something that should be fixed in wordfence or in change wp-admin ?

    Tks for your help.

    Hi @umik,

    We have had to add the plugin to our incompatibility list as it’s causing scans to fail for other customers too so the only information I have is that it can’t be enabled with Wordfence at the present time.

    Thanks,
    Peter.
