Insecure Direct Object References occur when an application provides direct access to objects based on user-supplied input. As a result of this vulnerability, attackers can bypass authorization and access resources in the system directly, for example, database records or files. Consider, User A uploaded a private photo at http://www.mysite/private/photo/5 and User B uploaded a photo at http://www.mysite/private/photo/6  (you should never use incremental ID's in the URL in the first place, use some random keys. This is just an example to show the concept.) Now User B shouldn't be allowed to view the photo of User A at http://www.mysite/private/photo/5, but many develope...

You did a successful Magento installation, the base theme is showing up and you are all good to go. Then you uploaded your theme and updated it from the Magento backend. Still, it’s not showing up. This is a problem that might eat up some of your time. Usually, a straightforward solution will fix it.

Once you’ve created the theme in the right folder, just run these commands: 

php magento cache:clear

php magento setup:upgrade 

php magento setup:di:compile and 

php magento setup:static-content:deploy --theme {vendorName}/myTheme2

That should do it!
