  • Resolved lion1968


    After updating the plugins to the version 1.5.1 from 1.4.9 generater crash of te system!
    I disable the plugins from ftp, and reactivating generates this error:

    Warning: require_once(rest/class.wp-super-cache-rest-get-settings.php): failed to open stream: No such file or directory in /web/htdocs/ on line 3

    Fatal error: require_once(): Failed opening required ‘rest/class.wp-super-cache-rest-get-settings.php’ (include_path=’.:/php5.6/lib/php’) in /web/htdocs/ on line 3

    I have wp V.4.8 with Tempera Theme, solutions for this ?

    I think the plugin didn’t install properly. Download it and install it again as that file is in the zip file.

    The plugins were already installed, i just updated from V.1.4.9 to 1.5.1 and the problem has occurred.
    I have deleted and reinsalled but the problem is the same.

    I’ve resolved this way:
    I installed the old version 1.4.9, activated and configured the plugins and updated to new version, now it works properly.

    Glad it’s fixed but that’s a bizarre problem you had.


    How do you exactly install and activate this version in FTP view?

    Plugin Author Donncha Ó Caoimh


    @tojiasja – Try the development version at as it’s fixed there. (unzip and overwrite the files in the wp-content/plugins/wp-super-cache/ directory)
    It will still say it’s 1.5.1 when installed so when 1.5.2 comes out you’ll receive an upgrade notice.

    Hey thanks for your reply @donncha
    When I try to change the files or rename them or do anything that would help it says that my permission is denied.
    Also there are two sets of wp-content files like
    wp-content and underneath wp-content-2
    Any idea what that might be about?


    Plugin Author Donncha Ó Caoimh


    OK, that’s annoying for you.

    First the easy bit. The second wp-content-2 directory is one made by your host I’d say. It’s probably a backup while they were doing something for you. Nothing to do with wp-super-cache.

    The permission thing is harder. You might have to get in touch with support at your host to get them to rename the wp-content/plugins/wp-super-cache directory. (Or write a small script that copies the previously uploaded development version files over the existing version, since it’s the web server running the script it will have permission to overwrite the files. Just ask your host, I think.)

    OK, thank you a lot for your support.
    One last question I have. Do I need to modify anything in the wp.config.php file since I read from somewhere that it could be a part of solution?

    Once again, thank you!

    You could edit it and remove the WP_CACHE and WPCACHEHOME lines.
