Thanks again for your excellent module, it's working very well. I have another
small issue.

When the cache is empty, the following warning is generated by ExaCSS when
loading a page:

Warning: Invalid argument supplied for foreach() in
/modules/ExaCSS/action.default.php on line 148

This message disappears after a page reload and can be reproduced by clearing
the cache again (as admin).

I've solved this by adding an extra check on line 148:

	if (glob(cms_join_path($cache_path,'exacss_*')))
	{
		foreach(glob(cms_join_path($cache_path,'exacss_*')) as $f)
		{
			unlink($f);
		}
	}

Maybe you can have a look at this.

Thanks,

Jasper
