"An administrator for your Account must read and accept the above Terms and Conditions. If these Terms and Conditions are not accepted, you will not be able to continue using AdSense."But of course it does not provide a fucking link/button to accept the Terms and Conditions it is demanding I accept!!!
The above issue was fixed when I let Firefox upgrade to the latest version, that's all I did. So if anyone themselves suddenly getting the above message when they try to check their AdSense account, update your browser!
