Title: [Plugin: WP Super Cache] cache tests failing Last modified: August 19, 2016 --- # [Plugin: WP Super Cache] cache tests failing * [stuart.thompson83@ntlworld.com](https://wordpress.org/support/users/stuartthompson83ntlworldcom/) * (@stuartthompson83ntlworldcom) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/) * 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/](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.

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/](http://www.viseum.co.uk/) to prime cache: OK Fetching first copy of [http://www.viseum.co.uk/](http://www.viseum.co.uk/): OK Fetching second copy of [http://www.viseum.co.uk/](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” * Thread Starter [stuart.thompson83@ntlworld.com](https://wordpress.org/support/users/stuartthompson83ntlworldcom/) * (@stuartthompson83ntlworldcom) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835726) * a quick question – can we use this development version of super-cache for general operation? or should we reinstall the non development version? * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835730) * 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. * Anonymous User 6077519 * (@anonymized-6077519) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835751) * 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. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835753) * 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. * Anonymous User 6077519 * (@anonymized-6077519) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835754) * 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) { } } * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835755) * 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. * Anonymous User 6077519 * (@anonymized-6077519) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-cache-tests-failing/#post-1835756) * The site is being cached we’ve used seositecheckup website to confirm this.

There’s no Supercache comment at the end. Perhaps use the debug system in the plugin to figure out what’s going wrong?
