Happy publishing. */ * ``` define( 'WP_DEBUG', true ); define( 'WP_DEBUG_DISPLAY', false ); define( 'WP_DEBUG_LOG', true ); ``` * Then try to reload the page. * A debug.log file should be created inside wp-content folder,which should contain error information in it, Please share the file with us. * [Harshad](https://wordpress.org/support/users/bornforphp/) * (@bornforphp) * [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15421203) * [@zyzz3031](https://wordpress.org/support/users/zyzz3031/) The correct code should be * ``` add_action('init','purge_cache'); function purge_cache(){ if (is_callable(array(WP_Optimize()->get_page_cache(), 'purge'))) { WP_Optimize()->get_page_cache()->purge(); } } ``` * Thread Starter [zyzz3031](https://wordpress.org/support/users/zyzz3031/) * (@zyzz3031) * [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15425715) * hi, i added the new code, but it does nothing. only new thing is, that under cache, the size and file count always stays at 0. * and i already before, every time i manualy load the cache, the first time i click the button i get the error message: an unexpecter request was received * [Harshad](https://wordpress.org/support/users/bornforphp/) * (@bornforphp) * [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15426824) * [@zyzz3031](https://wordpress.org/support/users/zyzz3031/) At the first attempt you see “an unexpecter request was received” but if you click the Preload button again it will preload the urls. * Thread Starter [zyzz3031](https://wordpress.org/support/users/zyzz3031/) * (@zyzz3031) * [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15426946) * Yes it will preload the cache if i click it another time. But the thing is, when i preload the cache the fist time, it never has the right amount. For excample: * I clear the cache, then preload. It says. 1mb 10 files * After clearing and preloading again it says. 2,5mb and 55 files. * And when i repeat that process again, it keeps telling me 2,5mb and 55 files. So thats the right cache. * But this problem was already before your code i tried. * And my main problem was/is that after the coreect cache size is loaded after the second attempt, i dont make any changes to the site. No plugins updates or any changes to the page, and every day the cache says some different size. * Sometimes its 17mb and 200 files, the next day its 0.3mb and 2 files…. * I really dont get it whats wrong. * If you want, you can have access to the site and see for yourself * Thread Starter [zyzz3031](https://wordpress.org/support/users/zyzz3031/) * (@zyzz3031) * [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15436269) * I have a second website at a different hoster and there is the same probleme. Site cache size changes everyday without the site changing anything. * Either i am to stupid to use this plugin and say cache the size and only reload everymonth or there is a big problem with your plugin Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘Cache size’ is closed to new replies. * ![](https://ps.w.org/wp-optimize/assets/icon-256x256.png?rev=1552899) * [WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance](https://wordpress.org/plugins/wp-optimize/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-optimize/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-optimize/) * [Active Topics](https://wordpress.org/support/plugin/wp-optimize/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-optimize/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-optimize/reviews/) * 8 replies * 2 participants * Last reply from: [zyzz3031](https://wordpress.org/support/users/zyzz3031/) * Last activity: [4 years, 5 months ago](https://wordpress.org/support/topic/cache-size-11/#post-15436269) * Status: resolved
