Page / browser cache incompatibility with PHP 5.4

  • I’m experiencing the same issue as others:

    Since upgrading to PHP version 5.4 on my (Godaddy) server the plugin breaks my site (returns just the white ‘Internal server error’ screen) unless Page and Browser caches are disabled.

    Is this something that is likely be resolved in the next update?

    Unfortunately I can’t just downgrade back to PHP 5.3 as Woocommerce now requires 5.4 as a minimum.

    Many thanks.

  • It is compatible with me and I was using php 5.4 until I upgraded to 5.5. Try clearing your cache and check your settings to make sure they are proper for your installation. You could also try using disk basic as opposed to enhanced.

    Hi and thanks for your reply.

    Just tried your suggestions but no joy unfortunately – even when I disable all other modules (leaving Page Cache enabled only) and clearing the cache I’m still getting the Server error.

    I tried using the ‘disk basic’ option but this had no effect.

    The only thing that seems to have any effect is (as others have mentioned) when the Debug Mode is enabled for the Page Cache. Then the site seems to load up without the Error. However, I’m rather reluctant to keep this activated as according to the description “Performance in this mode will not be optimal, use sparingly and disable when not in use.”

    Perhaps, though, this might provide some clue as to why the Page Cache is relying on Debug Mode to work?

    One thing I did notice from the Debug output was that the Header Info line is missing, as follows:

    <!– W3 Total Cache: Page cache debug info:
    Engine: disk: enhanced
    Cache key: mysite.co.uk/_index.html
    Caching: enabled
    Creation Time: 0.549s
    Header info:
    Link: <https://mysite.co.uk/&gt;; rel=shortlink
    X-Pingback: https://mysite.co.uk/xmlrpc.php
    Content-Type: text/html; charset=UTF-8
    –>

    Maybe this could have something to do with it?

    Hope someone is able to get to the bottom of this as I do really like the plugin but this incompatibility issue (when Debug Mode is disabled) is making it unusable.
