Title: Cache Plugin Error -1 Last modified: August 30, 2016 --- # Cache Plugin Error -1 * Resolved [Agrajag27](https://wordpress.org/support/users/agrajag27/) * (@agrajag27) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/) * Thanks so much for this well thought out plugin. It’s just what we’ve been looking for, forever! * Anyway, I enabled cache (via functions.php) and added the github cache plugin. It finds 1,300 posts, but when I tell it to cache it returns an Error -1. * [https://wordpress.org/plugins/related-posts-by-taxonomy/](https://wordpress.org/plugins/related-posts-by-taxonomy/) Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6866968) * Hi Agrajag27 * I can reproduce the bug. It’s fixed in the new version. Let me know if the new version fixes it for you. * [https://github.com/keesiemeijer/related-posts-by-taxonomy-cache](https://github.com/keesiemeijer/related-posts-by-taxonomy-cache) * In the coming month I will add a WP-CLI command to this cache plugin and make it more reliable.

Just so you know, I also added the line to functions.php for showing the cache state and I’ll be darned if I can find this display anywhere. hehehe * Thread Starter [Agrajag27](https://wordpress.org/support/users/agrajag27/) * (@agrajag27) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6866989) * Keesie, * Not sure what I’m seeing now. I load it, click “Cache Related Posts!” and immediately a pop-up appears that says just two things: * -1 OK * That’s it. * Plugin Author [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6866990) * > Just so you know, I also added the line to functions.php for showing the cache > state and I’ll be darned if I can find this display anywhere. hehehe * It should be in the toolbar at the top of your site (if you’re logged in as a admin). * So you still get the -1 after updating the plugin? [https://github.com/keesiemeijer/related-posts-by-taxonomy-cache](https://github.com/keesiemeijer/related-posts-by-taxonomy-cache) * I have some time tomorrow and look into it * Thread Starter [Agrajag27](https://wordpress.org/support/users/agrajag27/) * (@agrajag27) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6866992) * I’m logged in and admin, but no such item on my toolbar. * This -1 error is different than before. Before it was a red text with Error - 1 on it. This is a pop-up with -1. So apparently it got farther. * Thread Starter [Agrajag27](https://wordpress.org/support/users/agrajag27/) * (@agrajag27) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6866993) * Okay, this is interesting. I was looking for the plugin toolbox item on the Dashboard toolbox. It does NOT appear there. HOWEVER, it does appear there on the actual front page toolbar. * Sadly (but perhaps helpfully) it says, “Cache not used”. * Plugin Author [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6867008) * Yes, the cache log is only displayed on the front end of your site (when you’re logged in). * The “Cache not used” message could be better 🙂 It means it didn’t find a widget or shortcode in the current page, so there is nothing to cache or get from cache. * Can you update the cache extension again to 1.1. * Test with only these plugins active Related Posts by Taxonomy version 2.1.1 Related Posts by Taxonomy Cache version 1.1 * The minus 1 error is returned by the WP function check_ajax_referer [https://developer.wordpress.org/reference/functions/check_ajax_referer/](https://developer.wordpress.org/reference/functions/check_ajax_referer/) * It doesn’t think the ajax request comes from the cache extension’s settings page. It’s a security measure ensuring only valid requests are processed. I don’t know why it thinks your request isn’t valid though. * Thread Starter [Agrajag27](https://wordpress.org/support/users/agrajag27/) * (@agrajag27) * [10 years, 5 months ago](https://wordpress.org/support/topic/cache-plugin-error-1/#post-6867027) * (Reminder — See my reply to your reply in my Review) * I am testing this now with the site as is given that it’s a heavy read time for us and I have literally 25 plugins. Will have to wait for it to slow down a bit for full testing. * Also, went to a post page and the Toolbox area had two entries: * Post ID 12737 – cache not exists Post ID 12737 – caching posts… * The seems contradictory. * Lastly, with everything as is (full plugins loaded) it still just gives -1 pop- up. Will test this when it gets slow.
