AWS S3 console: An unexpected error occurred

I confirm that disabling the uBlock Origin plugin on Chrome fixes this issue. It also fixes other status issues such as the word 'error' under the 'access' column on the AWS S3 console page. Simply disable the plugin, refresh the page, and all is back to normal with the correct display status.

With uBlock Origin activated

After disabling uBlock Origin

I have not tested this on Firefox, Opera or Safari.

I had the same problem, but after deactivating CORS plugin (on Chrome) it started to work again.

Yes it works if you diasble the cors origin plugin.
