[Plugin: W3 Total Cache] Blank post.php after enabling XCache for object/database cache

    After installing XCache on the server and enabling it for object and database cache in W3TC, the site was loading faster than ever. There’s a huge downside, however. A few important links in my admin dashboard just render a blank, empty, white page:

    – “Add New” (post-new.php)
    – “Save Draft”
    – “Preview” (post.php, unless right-clicked and opened in new window… it then redirects to the proper preview URL that works)
    But worst of all though:
    – “Publish”

    If I disable object and database cache and empty all caches, the “Add New” page for instance works again.

    Also rendering a blank page when things are enabled (and not post related): “Deploy” in W3 Total Cache.

    Clicking the “empty only the opcode cache” also renders a blank page. Empty only the disk cache(s) works fine.

    “Add New” (post-new.php) shows the post form again with:
    a) XCache object cache DISABLED
    b) XCache database cache ENABLED
    But “Save Draft”, “Publish” etc. still don’t.

    With both caches disabled, every link and button works again.

    Did you check the error log? It seems you need to disable the authentication for the administration. Check the xcache documentation on how to do this.

    That helped and so far everything runs smoothly.

    Thanks so much for your indispensable plugin and your quick support!

    What exactly did you do to get this working I am having the same exact issue.

    I have edited:

    wp-content/plugins/w3-total-cache/ini/xcache.ini
    xcache.admin.enable_auth = Off

    Like stated in:

    https://xcache.lighttpd.net/wiki/XcacheIni

    Still getting the white pages, have checked every error log possible with nothing. The only cache I can clear is the disk cache not opcode.

    Thanks!

    I have the same problem. Get blank page after empyting cache. Have to log out of dashboard. When I log in again, cache was not cleared.

    Think we found answer. Admin authentication must be turned off:
    Description:
    xcache.admin.enable_auth = Off
    This needs to be set in php.ini.(cPanel = /usr/lib/php.ini)
    as well as,

    /home/XXXXX/public_html/testing/wp-content/plugins/w3-total-cache/ini/xcache.ini

    Follow up comments appreciated.
