Theme broken after upgrading to WordPress 4.5, missing stylesheet?

Updating to WordPress 4.5 broke my theme, ThemeWoot Emulate. It appears that perhaps a stylesheet is somehow missing. Example symptoms:

  • The mobile menu is shown by default
  • The top search box is being shown by default
  • The contact form modal is being shown by default
  • Various links are underlined and a different font

One thing I noticed was that, in the case where sections should be hidden by default, a .hide class is present, but there is no corresponding style being applied to that class.

I tried clearing the server and browser cache. I’ve tried deactivating all plugins and updating them, but there’s no difference.

It turns out that the ThemeWoot Emulate theme registers and enqueues a common.css file with the key of common in it’s themewoot.php (which is being included in functions.php).

This key is apparently conflicting with a wp-admin script being registered with the same common key, and so, instead of including Emulate’s common.css, it’s enqueuing and injecting the wp-admin common.min.css.

I edited the themewoot.php and namespaced the common key with a an emulate- prefix:


wp_register_style('common', $this->theme_url(). '/css/common.css', false, TWOOT_VERSION, 'all');



wp_register_style('emulate-common', $this->theme_url(). '/css/common.css', false, TWOOT_VERSION, 'all');


And that got things back in working order.

ThemeWoot doesn’t appear to be maintaining the Emulate theme anymore. In reality they should patch this and provide an update.

WordPress should seriously consider namespacing their core styles and scripts so that updates don’t affect themes like this. A simple wp- would have gone a long way here and saved me at least a few hours. Theme creators should also namespace all of their assets too so that they play nice with everything else.
