# Plugin causing javascript conflicts in the admin dashboard.

 * A few weeks ago I was having issues with some javascript functions in my wordpress
   admin dashboard. I couldn’t add new tags to a post, create new categories from
   the post edit page, or edit the permalink. After disabling my plugins one-by-
   one I narrowed it down to Custom Banners. I saw there was a recent update and
   thought that might have fixed it but it didn’t. Has anyone else had this issue?

 * Hey there!
 * This is a problem! Can you let me know what the specific error was you were having(
   ie, what error was being displayed in the console?)
 * I have tested in our development environment, both creating a New Category from
   the Edit Post screen as well as adding Tags to the post, from the Edit Post screen,
   and I have no issues doing so and see no errors in my console.
 * If you can help point us in the right direction we’ll definitely look into this!
   This is the first report we’ve received of this kind.
 * All the best,
    Richard

 * Here’s the error I’m getting in my console on the ‘Edit Post’ page:
    “TypeError:
   $ is not a function”
 * And it’s referencing this js file:
    ../custom-banners/lib/BikeShed/js/bikeshed.
   js?ver=1.0
 * As the console is open, another error keeps firing:
    “TypeError: e is undefined”
   and is referencing the WP load-scripts.php file
 * I just installed the plugin on a different site of mine and it’s causing the 
   same errors. It seems to wipe out anything that’s run by js/jquery in the admin
   dashboard… quick edit, permalink edit, add tags, add new category, etc.

 * Thanks!
 * There was a $/jQuery issue that was presenting on your site; the error you pasted
   pointed us in the right direction.
 * We have a check in place to prevent this error but it apparently isn’t working
   for you.
 * We will release a patch that fixes this issue for you — thanks again for letting
   us know!
