Title: Cache invalidation issue – static front page Last modified: August 20, 2016 --- # Cache invalidation issue – static front page * Resolved [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years, 3 months ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/) * Hello Stefano, * we found another bug. This applies to sites which have Settings –> Reading –> Front page displays set to “A static page”. * Cache for such page is not cleared when you publish a new blog post. Imagine you have homepage with a featured posts slider and some intro text and then a real blog page on /blog address with a classic list of recent posts. * Under these conditions, your cache.php sets the front page type “page” instead of “home”. The condition * `if (is_home() || is_front_page()) $data['type'] = 'home';` * Needs to be changed to: * `if (is_home() || is_front_page()) $data['type'] = 'home';` * Then the special front page cache is cleared properly when a new blog post is created. * This is crucial if the cache time is set to full day (your current default I believe) and it’s set to only clear the post, homepage and archive cache when a post is published/updated. * Could you please roll out a quick update version, so we don’t have to fix this by hand on a lot of our sites? * Thanks, Martin * [http://wordpress.org/extend/plugins/hyper-cache/](http://wordpress.org/extend/plugins/hyper-cache/) Viewing 15 replies - 1 through 15 (of 22 total) 1 [2](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/page/2/?output_format=md) [→](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/page/2/?output_format=md) * Thread Starter [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years, 2 months ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390116) * Hello all, * there was a new version one day ago and this was not addressed, so we can’t upgrade the plugin on our sites. * Of course, the original line is just this: * `if (is_home() || is_front_page()) $data['type'] = 'home';` * So the `|| is_front_page()` part is added. * Thanks, Martin * [martinjesus](https://wordpress.org/support/users/martinjesus/) * (@martinjesus) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390137) * Hi there, * I have my HOME page as a static page on Settings –> Reading. But it is not properly cleared when I do a post modification, although I’ve done the modification proposed by FolioVision. * (And Cache invalidation mode -> Only modified post; and “Invalidate home, archives, categories on single post invalidation” is checked). * Any ideas or help? * Thanks in advance for your support.

You typed the following: * > Under these conditions, your cache.php sets the front page type “page” instead > of “home”. The condition > if (is_home() || is_front_page()) $data[‘type’] = ‘home’; > Needs to be changed to: > if (is_home() || is_front_page()) $data[‘type’] = ‘home’; * . What is see is that both codes are identical. * Kind regards * Thread Starter [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390139) * Hello **mbrsolution**, * please read my second post. I made a mistake so I corrected it there. * Hello **martinjesus**, * either `is_front_page()` or `is_home()` should return true on your home page. * You should double check if your conditional tags behave properly on your home page, specially if you use a custom page template which pulls in posts from some category, or there might be a conflicting widget too. Both of that might reset your conditional tags and cause the above condition return `false`. * Other idea would be to also add `is_page( get_option('page_on_front') )`. However the goal is to provide an universal fix and is_front_page() should be enough. * More about conditional tags: [http://codex.wordpress.org/Conditional_Tags](http://codex.wordpress.org/Conditional_Tags) * There might be some other bug too. You can even enable Hyper Cache log (you need to uncomment the code in the plugin – look up function hyper_log()) and then add in your own logging to figure out the issue. * Thanks, Martin * [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390140) * Hello [@foliovision](https://wordpress.org/support/users/foliovision/), thank you for pointing to the second post. I was not sure that is why I ask. I do apologize for my blindness. * Kind regards * [evo252](https://wordpress.org/support/users/evo252/) * (@evo252) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390141) * Thank you so much FolioVision! * [evo252](https://wordpress.org/support/users/evo252/) * (@evo252) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390142) * Personally, I solved my issue by typing this (if it can help someone that may have a similar template): * `if (is_home() || is_front_page() || is_page_template( 'template-blogall.php')) $data['type'] = 'home';` * Because I’m using a custom page template, and it seems that front_page didn’t solved my issue. * [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390143) * Hi, I tested the settings above but in my situation it produces the famous screen of death 🙂 so I had to delete the following entry `|| is_front_page()`. Well I guess I don’t need the fix then. But very strange that you apply the fix and nothing happens to both of you. * Thank you anyhow I am sure someone will use this setting. * [martinjesus](https://wordpress.org/support/users/martinjesus/) * (@martinjesus) * [13 years, 1 month ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390144) * Hi FolioVision, mbrsolution and evo252, * First of all, thank you for your responses. * I’ve tried with “is_page( get_option(‘page_on_front’) )” and with “is_page_template(‘ myownhometemplate.php’ ) )”, and they do not work for me. * I will ask my template supplier for the way they identificate the home page, and if I arrive to a solution, I will let you know. * Thanks to all! * [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390149) * Hello all, just wanted to catch up and find out if your solutions above have been working fine. * Is there anything else one could add or edit to improve this? * Kind regards * Thread Starter [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390150) * Hello mbrsolution, * we had no further issues after applying our fix. We do a lot of custom template programming, so if we see any issues next time, we will drop a note in here. * However is there any Github repository for the plugin? That would make submitting bug fixes more efficient. * Thanks, Martin * [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390151) * Hello Martin, unfortunately I don’t know where you could add your fix to unless you ask Stefano Lissa. * I would like to ask you if you don’t mind what are your current settings for this plugin that works best for your website? I am trying to setup the best configuration to improve my website’s performance. * Kind regards * Thread Starter [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390152) * Hello mbrsolution, * we don’t really use any special config. If the home page or front page is properly recognized in the plugin (see above fix), then the caching time can be set to 1 full day without any problems. * We just make sure the theme switching works for the sites which use WPTouch Pro, so we exclude wptouch-pro-view and wptouch_switch_toggle cookies. We also update the list of mobile user agents to match WPTouch Pro. * Thanks, Martin * [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390154) * Hello FolioVision, thank you for your information. * I use WPTouch but not WPTouch Pro. The problem that I am having is that some pages or post don’t get cached correctly and on the PC or laptop browser the mobile view is displayed instead of the normal WordPress theme. * You mention that you exclude **wptouch-pro-view** and **wptouch_switch_toggle** cookies. Where do you enter these code in the plugin to exclude it. * Kind regards * Thread Starter [FolioVision](https://wordpress.org/support/users/foliovision/) * (@foliovision) * [13 years ago](https://wordpress.org/support/topic/cache-invalidation-issue-static-front-page/#post-3390156) * Hello mbrsolution, * you need to watch out for this when you test caching. * We have an older article about the mobile site setup process.
