Title: bootstrap.css.map file is missing Last modified: June 1, 2020 --- # bootstrap.css.map file is missing * Resolved [babasteve](https://wordpress.org/support/users/stevema93/) * (@stevema93) * [5 years, 12 months ago](https://wordpress.org/support/topic/bootstrap-css-map-file-is-missing/) * Hello, * The file “**bootstrap.css.map**” is missing in the Tabs Responsive extension, which creates an error in the error console of Google Chrome: * > DevTools failed to load SourceMap: Could not load content for [https://www.MYDOMAIN.fr/wp-content/plugins/tabs-responsive/assets/css/bootstrap.css.map](https://www.MYDOMAIN.fr/wp-content/plugins/tabs-responsive/assets/css/bootstrap.css.map): > HTTP error: status code 404, net: : ERR_HTTP_RESPONSE_CODE_FAILURE * I just wrote a message similar to Elementor support because there is also a missing“. map” file that produces an error with Chrome. * My website is closed, but you can check this error on all websites that use Tabs Responsive! For proof, you can check on wpshopmart: [Demo “Tabs responsive” on WPSHOPMART](http://demo.wpshopmart.com/tabs-pro-plugin-demo-for-wordpress/). 1. Open this page with Google Chrome 2. Right-click on the page, select “inspect” 3. Go to the “console” tab 4. As you can see, “**.map**” files are missing everywhere! * `NB1:` I have not checked on other browsers than Chrome `NB2:` I use the free version, but when we look at your page, obviously the error is also on the pro version. * To give you a research lead, on Elementor, users had found a way to work around the problem by adding the “.map” file by FTP. Unfortunately this file disappears with each update of the extension. – The discussion regarding the problem on Elementor can be found [here (Github)](https://github.com/elementor/elementor/issues/5151).– The page where Elementor’s “.map” file is located is [here (Github)](https://github.com/nolimits4web/swiper/tree/master/package/js).( I’m writing this to you so that you can see what the contents of the “.map” file look like, and you can better understand the type of problem). * The file “**bootstrap.css.map**” is supposed to be found here: / wp-content / plugins / tabs-responsive / assets / css / bootstrap.css.map * `WordPress:` 5.4.1 `Tabs Responsive:` 2.0.3 * Pending your response, and hoping for a fix in the next patch update, thank you for your attention, cordially.

Here’s how they did it: * – Fix: Removed source map comment so so browsers don’t look for source map in Swiper library. – Editing the file swiper.min.js in folder wp-content / plugins/ elementor / assets / lib / swiper and remove this: // # sourceMappingURL = swiper. min.js.map * I have not tried it but I imagine that it is enough to apply this method to Tabs Responsive for boostrap and the others. But as I do not know much in the code, I do not know if these “.map” files have or will have an importance for responsive Tabs. * [preetam27](https://wordpress.org/support/users/preetam27/) * (@preetam27) * [5 years, 12 months ago](https://wordpress.org/support/topic/bootstrap-css-map-file-is-missing/#post-12929993) * hi [@stevema93](https://wordpress.org/support/users/stevema93/) , * glad that your issue has been resolved..we will consider this issue..as we haven’t added .map file of bootstrap.. * thanks. * Thread Starter [babasteve](https://wordpress.org/support/users/stevema93/) * (@stevema93) * [5 years, 10 months ago](https://wordpress.org/support/topic/bootstrap-css-map-file-is-missing/#post-13096953) * The problem was resolved on elementor but not on Tabs Responsive, and the update that appeared today did not resolve the problem.
