Support » Plugin: Autoptimize » Change Directory

  • Resolved scottstone


    My server (Pantheon) does not allow writing to any directory other than wp-content/uploads for security reasons. Is it possible to move my cache directory into wp-content/uploads?

    Per this FAQ it sounds like I can but I also suspect this is an outdated or different solution.

    Can I change the directory & filename of cached autoptimize files?
    Yes, if you want to serve files from e.g. /wp-content/resources/aggregated_12345.css instead of the default /wp-content/cache/autoptimize/autoptimize_12345.css, then add this to wp-config.php:


    I added these two lines to the end of my wp-config.php file using /uploads/ instead of /resources/ but it did not work. I assume this does not actually move the directory.

    Pantheon suggested I set-up a symlink ( using Git but this is getting beyond my technical level. I am not a developer. Any help moving the cache directory to a sub-directory of uploads is much appreciated.

    hi scott;
    just did a quick test and


    does do the trick. I do however remember reading that the place where you add these, is important, so maybe try adding this more at the beginning of wp-config.php?

    hope this helps,

    There is small error log appers, when ‘AUTOPTIMIZE_CACHEFILE_PREFIX’ is set to ”, when you want files names to contain only md5 hash:

    "strpos(): Empty needle" in file "classes\autoptimizeCache.php on line 131"
    ( strpos($file,AUTOPTIMIZE_CACHEFILE_PREFIX) !== false) )

    So you have to pass at least ‘_’ for ‘AUTOPTIMIZE_CACHEFILE_PREFIX’.
