    We are using wp-super-cache and it seems to be helping our site load a bit faster but we are testing errors or “fails” with the “Test Cache” in the “Tester & Contents” tab of this plug-in.
    Please see the report below. Does this mean the site is working fine or a problem needs resolving?
    Please note that we are also testing the cache using a third part tool from http://www.seositecheckup.com/ – this tool is also reporting that the caching is not operating.

    “Test Cache” in the “Tester & Contents” report:
    Cache Tester
    Test your cached website by clicking the test button below.
    Fetching http://www.viseum.co.uk/ to prime cache: OK
    Fetching first copy of http://www.viseum.co.uk/: OK
    Fetching second copy of http://www.viseum.co.uk/: OK
    One or more page requests failed:
    • Page 1: 0 ()
    • Page 2: 0 ()
    The pages do not match! Timestamps differ or were not found!

    Try the development version of WP Super Cache on the plugin download page as it saves each page when it does the test so you can compare them manually.

    Thanks.
    We have loaded this version of super-cache and the error messages no longer appear:)
    However!! For absolute clarirty these messages were:
    Fetching http://www.viseum.co.uk/ to prime cache: OK
    Fetching first copy of http://www.viseum.co.uk/: OK
    Fetching second copy of http://www.viseum.co.uk/: OK
    One or more page requests failed:
    • Page 1: 0 ()
    • Page 2: 0 ()
    The pages do not match! Timestamps differ or were not found!

    So, with the development version of wp-super-cache these errors are no longer reported but the symptom still persists ie the when visiting the website for the first time,it seems like the server was asleep and needs waking up before pages start to load quickly!

    Therefore could the orgigonal reported problem still be to blame? ie “One or more page requests failed”

    a quick question – can we use this development version of super-cache for general operation? or should we reinstall the non development version?

    Currently you can and it’s nearing release of a new version so when a new version comes out you’ll still be notified of the upgrade.

    You should probably try the debug system in the plugin to figure out why it’s not caching. Log to a file, not email.

    Hi donncha, do you know what it means by

    (taken from Stuart’s post above)

    One or more page requests failed:
    • Page 1: 0 ()
    • Page 2: 0 ()
    The pages do not match! Timestamps differ or were not found!

    I was wondering if the slideshow could be the cause, since it changes every few seconds with written content within it aswell.

    The error returned from wp_remote_get() isn’t in the form it’s supposed to be. I don’t know why. You could edit wp-cache.php and around line 908 (of version 0.9.9.8 released today) add this code:

    var_dump( $page ); var_dump( $page2 );

    That will tell you what exactly what was returned by the cache tester.

    I got the following, not sure what it means

    array(4) { [“headers”]=> array(0) { } [“body”]=> string(0) “” [“response”]=> array(2) { [“code”]=> int(0) [“message”]=> string(0) “” } [“cookies”]=> array(0) { } } array(4) { [“headers”]=> array(0) { } [“body”]=> string(0) “” [“response”]=> array(2) { [“code”]=> int(0) [“message”]=> string(0) “” } [“cookies”]=> array(0) { } }

    Thanks, that’s bizarre. That should be filled with error messages. I’m not sure why that’s happening for you. Test it manually by reloading the homepage I guess.

    The site is being cached we’ve used seositecheckup website to confirm this. We’re just concerned about the severity of this error.

    You probably don’t need to worry about it but if you are worried you’ll have to debug wp_remote_get() to figure out why that’s breaking 🙁

    I’m using V 0.9.9.8 and got this when i tested the cache:

    Test your cached website by clicking the test button below.

    Fetching http://www.creative-i.info/ to prime cache: OK
    Fetching first copy of http://www.creative-i.info/: OK (1.html)
    Fetching second copy of http://www.creative-i.info/: OK (2.html)
    The pages do not match! Timestamps differ or were not found!

    Creative-i – click on 1.html and 2.html and compare them manually. That might give you a clue as to why the test failed.

    I just did a test on the SEO site mentioned above and it appears that pages are not being cached, yet there’s nothing on the WPC page that indicates that it’s not caching:

    ‘It does not appear that you are caching your pages.’

    And in-advertantly coughed up another problem with an Amazon/Google/Alexa search api?

    Donncha:

    Both pages look identical but if I’m not caching the pages?

    B

    I looked at your site and it looks like Supercache isn’t turned on at all. There’s no Supercache comment at the end. Perhaps use the debug system in the plugin to figure out what’s going wrong?
