Fatal error on Settings Page with other 2FA plugin installed

Hello, @timothyblynjacobs

Any update about this fix ?

I opened a ticket support for the same reason (except that it concerns ithemes security pro).

Thanks for the temporary workaround.

Update : The temporary workaround doesn’t work with pro version 🙁

By bad : iThemes licence information had disappeared so I didn’t get the last version.

Unfortunately, I still have this error with the latests (7.0.3) :
Fatal error: Cannot declare class Two_Factor_Provider, because the name is already in use in /home/clients/xxx/xxx.fr/www/wp-content/plugins/ithemes-security-pro/core/modules/two-factor/providers/class.two-factor-provider.php on line 13

The bug fix only works in combination with the Two Factor plugin.
It probably won’t work for any other conflicting 2FA plugin (if any).

Ok, I see.

To rule out that the 7.0.2 -> 7.0.3 update failed, check for the code below in the ithemes-security-pro/core/core.php file:

	/**
	 * Checks for compatibility with existing plugins,
	 * and disables the respective ITSEC modules if needed.
	 */
	public function compat_checks() {
		// The Two-Factor feature plugin and ITSEC Two-Factor cannot be used at the same time.
		if ( defined( 'TWO_FACTOR_VERSION' ) ) {
	 		ITSEC_Modules::deregister_module( 'two-factor' );
			ITSEC_Modules::deregister_module( 'pro-two-factor' );
		}
	}

If that piece of code does not exist, download the 7.0.3 .zip file from iThemes Member Panel. Then delete the current wp-content/plugins/ithemes-security-pro folder and upload/extract the 7.0.3 .zip file manually(if not already). Then retry.

For now I’m assuming the 7.0.3 release fixed the issue, but you never know 😉 Keep me posted.

Thanks your very much for answering @nlpro. (I didn’t understand that you were part of the team)

You’re welcome. Though I’m not part of iThemes.
Just interested in solving issues 😉

Ok, looks like the bug is not completely fixed in Pro.
Do you have any of the following modules enabled:

• User Logging
• Trusted Devices

It looks like the 2 Pro modules mentioned above (and the CLI module) still try to instantiate the ITSEC_Two_Factor_Helper class which performs a require_once of the core/modules/two-factor/providers/class.two-factor-provider.php file.
