I’ve gotten random 404 Errors. Examples: 1. When trying to upload the demo content 2. When trying to delete one of the sample trainer profiles 3. When clicking on the Updates menu item
After I go back and perform the action again, it will either result in another 404 Error page – or it will work.
Can you pls check the server error log and see if any errors displayed?
and Also pls enable debugging by setting WP_DEBUG to true in wp-config.php file in the wordpress root folder and check if it throws any error.
