The Router do not works correctly

I was made a component, and a module for.
Well, after put the URL to SEF, the component URL is missing the menu item and do no retrieve any content, only a blank or error page appointing to router.
The link comes like: /component/mymemberslist/member/3&Itemid=127
But in a blank page !!!!
My Joomla is 3.6.2

Hy there i can see your post and i must say

Check SEF Settings:

Ensure that SEF URLs are enabled in Joomla's global configuration. Go to "System" -> "Global Configuration" -> "SEO Settings" and make sure "Search Engine Friendly URLs" is set to "Yes" and "Use URL Rewriting" is also set to "Yes."
Check .htaccess File: ADP Workforce Now
Ensure that your Joomla site has an .htaccess file in its root directory. This file is essential for URL rewriting to work correctly. If you don't have one, you can typically find a sample .htaccess file included in the Joomla installation package.
Menu Item Configuration:

Make sure that you have a menu item created for your component. The Itemid in the URL is crucial for Joomla to determine how to display the content. If the menu item is missing or misconfigured, it can lead to blank or error pages.
