# DevTools failed to parse SourceMap

 * To Whom It May Concern,
 * I have noticed this error message in the chrome browser console consistently 
   ever since Data Tables by Supsystic version > 1.9.86. Version 1.9.86 does not
   have this problem.
 * DevTools failed to parse SourceMap: [https://devel.world-of-waterfalls.com/wp-content/plugins/data-tables-generator-by-supsystic/src/SupsysticTables/Core/assets/js/lib/jquery.contextMenu.min.js.map](https://devel.world-of-waterfalls.com/wp-content/plugins/data-tables-generator-by-supsystic/src/SupsysticTables/Core/assets/js/lib/jquery.contextMenu.min.js.map)

 * Any ideas what changed in the subsequent versions that would have caused this
   problem? I’ve also seen in other threads the same error message when screen shots
   are provided.
 * And can I ignore this kind of error since I need to update to patch a security
   flaw that is only solved in version 1.9.92?
 * Thanks

      Reason: added link to point out error occurs when going to the plugin's menu
      in the WP backend

 * Hi,
 * I am currently running Data tables Generator by Supsystic version 1.9.94.
 * This console error also shows up on the front end of the site.

   submit a new topic.
