Latest update causes fatal errors

I just updated Solid Security (to 8.0.4) on a few of my sites and I got a fatal error on all of them:

Fatal error: Uncaught Error: Interface ‘iThemesSecurity\Contracts\Import_Export_Source’ not found in /home/customer/www/groenteavontuur.nl/public_html/wp-content/plugins/ithemes-security-pro/core/modules.php:16 Stack trace: #0 /home/customer/www/groenteavontuur.nl/public_html/wp-content/plugins/ithemes-security-pro/core/core.php(125): require() #1 /home/customer/www/groenteavontuur.nl/public_html/wp-content/plugins/ithemes-security-pro/ithemes-security-pro.php(99): ITSEC_Core->init(‘/home/customer/…’, ‘Solid Security …’) #2 /home/customer/www/groenteavontuur.nl/public_html/wp-settings.php(462): include_once(‘/home/customer/…’) #3 /home/customer/www/groenteavontuur.nl/public_html/wp-config.php(110): require_once(‘/home/customer/…’) #4 /home/customer/www/groenteavontuur.nl/public_html/wp-load.php(50): require_once(‘/home/customer/…’) #5 /home/customer/www/groenteavontuur.nl/public_html/wp-admin/admin.php(34): require_once(‘/home/customer/…’) #6 /home/customer/www/groenteavontuur.nl/public_html/wp-admin/index.php in /home/customer/www/groenteavontuur.nl/public_html/wp-content/plugins/ithemes-security-pro/core/modules.php on line 16

Not sure if its just me, but I got it on multiple websites. I now turned the plugin off by renaming the folder, but I don’t want to keep it off too long offcourse.

I hope someone can help me! 😊
Thanks in advance!

Best regards,
