Google Chrome 53.x
If you have saved a CA UIM username and password in the Chrome browser, the browser automatically fills in that CA UIM password in some fields in the snmpcollector v3.2x probe UI. The incorrect information in these fields causes an error in the snmpcollector UI that appears to result in the loss of profiles.
To remove this behavior, in "manage passwords" section of the advanced settings in Chrome, delete the password for the admin console and UMP. The workaround is to Disable Chrome from automatically filling in credentials in the snmpcollector probe UI.
