magento 1.9.3.1 backend 404 Not Found 1 when go to link https://domain_name/index.php/admin

[Kekaron]

Admin Panel was working fine for me until yesterday I refresh the cache after making some changes to the homepage's cms widgets and static blocks. I tried first on localhost and was working fine.  When I did the same thing on the server it worked fine. But after some time it just shows 404-page error on the server and the front_end is working properly. 

Need Help Urgently.

Thank You.

Hi @Kekaron,

Can you check on your server if the admin path was changed?

You can check at:

/path/to/magento/app/etc/local.xml

Normally, at the end of the file, you should find something like:

    <admin>
        <routers>
            <adminhtml>
                <args>
                    <frontName><![CDATA[admin]]></frontName>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

If the value of <frontName> is different to admin you won't be able to access using that URL.
