Nonce Error When Plugin Is Activated

Hi – I would like to know why I receive an nonce error in the URL whenever I activate a plugin while logged in as a multisite user. This is the output in the URL “_error_nonce=49a2c54fb0”. It seems like the “49a2c54fb0” is some kind of log number.

Is there a way to view the log of nonces? If so, how is this done?
