It's known that the used @import replacement utility from the „Minify“ project doesn't resolves URL's. It's not a real problem, because such @import rules will simply be not replaced.

The compress.ignore configuration options are not used for scripts which should be merged. This is simply not possible without to disable the compressing in total.

The defer and rev attributes are completly ignored. Don't worry, because they are not supported by the most major browsers.

If you experience problems after the minifcation, compressing or merging processes, you should continue reading at the Troubleshooting chapter.

The file ending „.gz.css“ or „.gz.js“ are reserved by this extension. If you want to use it for own files which are not gzip compressed, you will need to adjust the .htaccess configuration.

Any embedded contents, except the javascript code inside the body, are automatically added to temporary files. It's a small hidden feature which shouldn't harm.

The default ordering of the files after the processing is: CSS, CSS inside conditional comments, Javascript (Head), Javascript (Body).

The addBeforeBody option doesn't merges the javascripts of head and body. You will have at least two referenced files afterwards. It's a known bug which can't be resolved easily. But in most cases you can simply ignore it.
