[Plugin: W3 Total Cache] CSS Background images from Amazon S3

I’ll check if this is a known bug, but for now you can simply remove the https://domain.com/ from your CSS file, leaving a path that starts with /wp-content/ and you’ll be all set (after rebuilding your minify cache).

Can you use the bug submission form in the support tab to send the original CSS file also?

Sorry to take so long to answer. It’s been a long week…

Here is my original CSS (don’t think I need to use the submission form unless it helps you in some way):

https://www.cozmoslabs.com/wp-content/themes/cozmic/style.css

As you can see all the background:url(images/my_image.jpg) declarations are relative to the css file.

Just as a sidenote the @import’s at the top are also relative to the directory where this file resides and are loaded from the parent theme (since I’m using a parent theme <-> child theme relationship). If possible in the future all @import declarations in the main css file should be included directly by W3TC if possible. Those imports add each another http request.

I wouldn’t ask if it didn’t help. Your current settings and the minify error log etc are included with the submission to facilitate proper support.

This is a limitation of the minify library and a known issue. Other minification engines will be added later, hopefully addressing the issue, meanwhile it doesn’t appear like the minify team is very active with the project, which has made it difficult to move on with the W3TC project as a whole.

That makes sense. I’ve sent a bug report from the backend!

Thank you.

https://www.cozmoslabs.com/wp-content/themes/cozmic/style.css should be specified as: wp-content/themes/cozmic/style.css

Unless a file has a query string variables, the path should be relative.

What I did was simply ctrl F my css files and replaced my domain with the CDN url which essentially fixes this problem.

Notepad++ can easily find / replace.

If you use relative paths as appropriate this step is not necessary.

Yup. That did the trick. I knew I was missing something.

Thank you so much for your support.

You’re welcome.
