 * Hi,
 * Great plugin, but the latest version seems to have an issue, as I’m seeing lots
   of 404 errors in my logs for:
 * [https://mysite/wp-content/plugins/jquery-collapse-o-matic/light_style.css?ver=1.6](https://mysite/wp-content/plugins/jquery-collapse-o-matic/light_style.css?ver=1.6)
 * Can you please advise, or fix this ASAP?
 * Many thanks,
    Martin

 * have you cleared your cache? This sounds like it’s most likely commign from and
   old, cached version of the css file as:
    [https://mysite/wp-content/plugins/jquery-collapse-o-matic/light_style.css?ver=1.6](https://mysite/wp-content/plugins/jquery-collapse-o-matic/light_style.css?ver=1.6)
   has been moved to: [https://mysite/wp-content/plugins/jquery-collapse-o-matic/css/light_style.css?ver=1.6](https://mysite/wp-content/plugins/jquery-collapse-o-matic/css/light_style.css?ver=1.6)
 * Can you quickly check that and get back to us?
 * Update: we just double checked, and everything is where it should be. highly 
   probable that the the cache just needs to be cleared/updated.
    We’ll leave this
   topic open until you get back to us with your findings.

 * Hi,
 * I have cleared my CDN cache but I’m still seeing some 404’s, I have now added
   a redirect, and will see if that stops the 404 errors from now on.
 * Let me be clear this error is being generated by customers all over the world
   visiting my site.

 * Well, if you share a link to the site, we might be able to be of more assistance.
   
   Again, 1) verify it’s being _served fresh_ from your server and not from some
   caching plugin. 2) check to see that the file does, exist where it should: wp-
   content/plugins/jquery-collapse-o-matic/**css/**light_style.css
 * Last option would be to deactivate, delete, reinstall and reactivate the plugin
   from the WordPress repo.
 * Just to be transparent, here is a link to [the source](https://plugins.trac.wordpress.org/browser/jquery-collapse-o-matic/trunk/collapse-o-matic.php)
   clearly showing that the style is being loaded from the css sub directory:
    `
   wp_register_style( 'collapseomatic-css', plugins_url('css/'.$this->options['style'].'
   _style.css', __FILE__) , array (), '1.6' );`
 * And all css related files are located in this sub directory:
