Fixing "SourceMap" error messages in the Development Tools Console caused by Chrome extensions:

Examples caused by McAffeMcAfee extensions:

If you are developing, then you need "Enable javascriptJavaScript source maps" and "Enable CSS source maps" checked to be able see your source code in Chrome Developer Tools. Unchecking those takes away your ability to debug your source code. It is like turning off the fire alarm instead of putting out the fire. You do not want to do that.

Instead you want to find the extensions that are causing the messages and turn them off. Here is how you do that:

  1. Go to the three dots in the upper right hand corner of Chrome.
  2. Go to "More Tools" and click on "Extensions".
  3. Do this for one extension at a time until no more "SourceMap" errors are in the console:
    1. Turn off the extension by sliding the switch to the left.
    2. Reload the page that you were using the Development Tools on.
    3. Check if any of the "SourceMap" error messages disappeared.
      1. If any did, then that extension was causing those messages.
      2. Otherwise, that extension can be turned back on.

After determining which extensions caused the issue either:

  1. If you need it, then contact the maker to have them fix the issue.
  2. Otherwise, remove the extension.
