Hi Everyone,

I am getting 404 page not found on some pages of admin panel like product page, design configuration , bundle product , etc. My frontend is working fine but backend magento admin is messed up in some pages. 

Below are snapshot for same.

I have flushed cache several time, deployed and updated using command. But nothing is working. Please help.

Hello tjain90,

Your best bet would be to check your Magento System Log (var/log/system.log) and see what errors show there. You can also paste the errors here and one of us should be able to assist further.

Cheers!

Please make sure you have following 

1. Deploy mode is set to developer

2. All cache is disabled 

Then in index.php located in the root folder put following 2 lines

This will help to understand any php error are there 

ini_set("display_errors","on");
error_reporting(E_ALL);
