I'm using Joomla 3.4 stable and I seem to be getting Javascript console messages:

JQMIGRATE: Logging is active
JQMIGRATE: jQuery.browser is deprecated

Debug mode in Joomla is turned off so I don't know why these are displaying and I haven't modified any core code. Any idea?

I had the exact same thing a couple of days ago when testing some avatars in our extension.

The message you've provided is being produced by Community Builder as it's importing jQuery Migrate (uncompressed).

You can either, download the minified version and replace it, or open the current file and replace:

jQuery.migrateMute = false


jQuery.migrateMute = true
  • Thanks for that. I'm not actually using Community Builder so mush have been another extension that has caused the problem. Either way resolved with your solution. Thanks

  • Joomla core uses jQuery migrate by default see the code at github.com/joomla/joomla-cms/blob/staging/libraries/cms/html/… Mar 4, 2015 at 16:37
  • @GeorgeWilson - Joomla imports minified files by default. jQuery migrate does not throw this error in the minified version, so unless the OP has debug mode enabled, it's not a core Joomla related issue
