    Minify doesn’t work.

    Failure: recently an error occurred while creating the css / js minify cache: some files were unavailable, please check the settings to ensure the site is working as intended.

  • I had this problem, and had to clear the cache then verify all the individual file URLs. You can verify the URLs when you go into manual model and add the individual files.

    If it 404s then check the file exists/linked properly and/or redirects to the proper place.

    Its’ been a ‘interesting’ time learning this plug-in!

    well i’ve got the same problem and I don’t understand very well what steps follow to solve the problem… if CSD_Images or somebody can explain better it would be appreciated.

    I’m no expert at this but a bit of tinkering yesterday gave me the solution:

    Performance: General

    Under minify panel enable and set to manual, leave everything else as is.

    Performance: Minify

    You will see the option to clear cache next to this is the help wizard.

    Click on this and choose the scripts you want minified. Then check the URLs as it’s only checking for links, not for files actual existence. This caught me out as one of my files as moved by accident on the server.

    Once you have chosen your files and back to the Performance interface you will see your list of files, next to that you will see delete/verify. It’s here you will check for the files existence.

    Alternatively you could add each script individually and test exhaustively.

    Please see my post in this link:

    Basically it appears that after upgrading the minify arrays are getting messed up and need to be manually deleted before re-adding the files and enabling minify.

    Sorry for the trouble. Are you still having issues with the latest release?

    Actually since the last release I start with this problem (

    I have the same problem, and it appeared with WordPress 3.2.

    Ah, please disable that option for now it’s not very reliable. If you want to submit bug submission forms about it for testing, that’s also cool.

    I don’t know if this applies, but see my post about automatic minifying errors:
    (btw, I meant to say *Important* parsing error found with automatic minify)
    In the minifying process, incorrect .js code was generated. You’ll see what I mean in my post. Good luck!
