After updating from 2.4.0 I now get 404 page error when saving a page and also lost market place in the admin menu.
kindly check and update your PHP version to 7.4 if it's an older version.
also, you need to check the 3rd party extension version if they have an update for Magento 2.4.1 as it has a lot of updates and many older version modules are not updated yet.
RE : Marketplace:: Web Setup Wizard is removed from admin & you need to install the extensions from the command line only. REF
kindly Accept as a Solution if this works for you and give Kudos
on my other site it's still there and it's also on 2.4.1 why did they remove it? it made updating easier and for security issues I have ssh disabled
Kindly check in your index.php if you are able to exit there, if not, then configure your Base URL by running below command :
php bin/magento config:set web/unsecure/base_url http://example.com/ php bin/magento config:set web/secure/base_url https://example.com/
Let us know if it works !
