whmcs eula-accept issue

've just upgraded from WHMCS 7.5.2 to 7.6.0 today, everything was smooth but when I tried to login,
it showed me the "End User License Agreement" page. When I clicked on the "I Agree" button, it sent me to 404 page not found error. For your information, I'm currently using a custom whmcs admin directory so the link end up like this www.something.gov/customadmindir/eula-accept

I can't proceed to the dashboard for now. Help me, its urgent!

Troubleshooting Problems Accepting EULA After Update


After applying the WHMCS 7.6 update, upon first logging to the administration area, it is necessary to read and agree to an updated License Agreement (EULA).
In some circumstances, clicking the Accept button may reload the page or result in a 404 error:

The requested URL /admin/eula-accept was not found on this server.


This is caused by a mis-configured Friendly URLs setting, causing the Accept button to point to an unroutable path on your server.


The Friendly URL setting can be reset to the basic value by executing the following SQL command against the WHMCS database:

UPDATE `tblconfiguration` SET value ='basic' WHERE setting='RouteUriPathMode'; Refresh the License Agreement page in your browser.
The updated Agreement can now be accepted successfully
