We've been trying to migrate our current M184.108.40.206 to M2.3.3 but we ran into an exception we can't seem to solve/ get rid of. This occurs wherever we go on the website; we cannot access the storefront or admin. The errors says:
Exception #0 (ReflectionException): Class Magento\Captcha\Model\Recaptcha does not exist
The full message: https://pastebin.com/nGqMtnKJ
We tried all the solutions we could find and already posted on the official Magento forum but so far the suggested solutions did not have any effect. For reference: https://community.magento.com/t5/Magento-2-x-Programming/Migration-M1-to-M2-but-ReflectionException-Class-Magento-Captcha/td-p/325657
Anyone got an idea what might cause this? Thank you!
