Title: [Plugin: FT Calendar] Generates false 404 errors Last modified: August 20, 2016 --- # [Plugin: FT Calendar] Generates false 404 errors * [mished](https://wordpress.org/support/users/mished/) * (@mished) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/) * I’ve installed this plugin on a multisite. * It generates false 404 errors at this URL: * [http://domainname.com/wp-content/plugins/ft-calendar/includes/js/jquery.tools.min.js?ver=3.2.1](http://domainname.com/wp-content/plugins/ft-calendar/includes/js/jquery.tools.min.js?ver=3.2.1) * I’ve got my 404s monitored by two error-logging plugins and they both show the same results: false 404s from this FT CALENDAR URL. * Great plugin otherwise. * [http://wordpress.org/extend/plugins/ft-calendar/](http://wordpress.org/extend/plugins/ft-calendar/) Viewing 6 replies - 1 through 6 (of 6 total) * Thread Starter [mished](https://wordpress.org/support/users/mished/) * (@mished) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2294749) * OK, need to clarify. * The faulty URL is actually: * [https://domainname.com/wp-content/plugins/ft-calendar/includes/js/jquery.tools.min.js?ver=3.2.1](https://domainname.com/wp-content/plugins/ft-calendar/includes/js/jquery.tools.min.js?ver=3.2.1) * So anytime ANY page on the site is visited, this URL generates a 404. * Note the “https”. I actually do not use a SSL certificate on my site, so don’t understand why FT Calendar is generating a HTTPS. * [Lew Ayotte](https://wordpress.org/support/users/layotte/) * (@layotte) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2294917) * Does visiting that URL manually still produce a false 404? * Lew * Thread Starter [mished](https://wordpress.org/support/users/mished/) * (@mished) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2295020) * Thinking the problem I encountered is site-specific, I just started monitoring 404 on another site where I also have this calendar plugin installed * Yes, it is causing the same problem. It doesn’t matter which page/post I view on the site, a 404 error is triggered. * **A 404 error occured at the following url: mydomainname.com/wp-content/plugins/ ft-calendar/includes/js/jquery.tools.min.js?ver=3.2.1 ** * Referrer: [http://mydomainname.com/postname/](http://mydomainname.com/postname/) * What impact would all these false 404s have on my site in terms of SEO? I like this plugin so wouldn’t mind all the false 404s as long as they don’t have any adverse SEO effect (site visitor experience is not adversely affect in any way, I think). * Are these(generating the false 404s) a resource hog? * [Lew Ayotte](https://wordpress.org/support/users/layotte/) * (@layotte) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2295040) * What plugins are you using to monitor 404s? Also, are these Linux based servers running Apache? * I don’t think this would affect SEO at all… if you can get to the URL then the web crawlers should be able to too. * Lew * [Nando](https://wordpress.org/support/users/elnando/) * (@elnando) * [14 years, 3 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2295136) * The issue with the 404 error is ’cause is misssing the jquery.tools.min.js in the ft-calendar/includes/js/ directory…you need to download the file [http://jqueryb.googlecode.com/files/jquery.tools.min.js](http://jqueryb.googlecode.com/files/jquery.tools.min.js) to that directory * The Google PR and Bing/Yahoo SEO statics show 404 error with this file, so in my opinion YES affect SEO. I have a IDS in one of my site and show the same missing file on any page * [Lew Ayotte](https://wordpress.org/support/users/layotte/) * (@layotte) * [14 years, 3 months ago](https://wordpress.org/support/topic/plugin-ft-calendar-generates-false-404-errors/#post-2295137) * Nando, have you updated to the latest version?
