Title: WordPress Theme Editor Stylesheet File Editor Error Last modified: March 16, 2019 --- # WordPress Theme Editor Stylesheet File Editor Error * [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/) * I have wordpress website. I am trying to change css code under Theme Editor> Stylesheet. But when i click on update file button an error occurred. * `Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP.` * Can anyone let me know how do i solve this problem?

Can you try the [Health Check](https://wordpress.org/plugins/health-check/) plugin to see if it finds the problem? * Thread Starter [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11328776) * [@joyously](https://wordpress.org/support/users/joyously/) is there any other way to check and solve this problem. I cannot add css all the time using ftp. I find Theme Editor easier way to add/edit css. * [Joy](https://wordpress.org/support/users/joyously/) * (@joyously) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11330636) * Did you try the Health Check plugin? What did it say about file permissions? Why are you trying to do CSS through the file editor? If it’s a parent theme, it will be overwritten when it is updated. If it is a child theme, you should be making updates locally and FTPing them to your site. Either way, you can change CSS in the Customizer under Additional CSS and you don’t have to change any files. Or use a plugin to add CSS that stays when you switch themes, and you still don’t have to edit a file. * Thread Starter [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11342087) * [@joyously](https://wordpress.org/support/users/joyously/) Yes, I tried this plugin too. After installing this plugin I click on the start button and after a few seconds my website stop working and all my plugins was automatically deactivated. I had no idea what’s going on with my website. I had installed this plugin to solve my problem. But I was in new problem. 🙁 - This reply was modified 7 years, 2 months ago by [jsima](https://wordpress.org/support/users/jsima/). * Thread Starter [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11343374) * [@joyously](https://wordpress.org/support/users/joyously/) I am changing css under wp-admin/theme-editor.php section. I think all css is stored in this section then how it will be overwritten? Could you please explain this. * Waiting for your kind reply. * Moderator [Steven Stern (sterndata)](https://wordpress.org/support/users/sterndata/) * (@sterndata) * Volunteer Forum Moderator * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11344099) * What “start” button? * Did you install [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)? * The information about writability (if that’s a word) should be on the opening screen. * It may be that you do not have write permissions for `wp-contents/themes/yourtheme`. * Thread Starter [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11346281) * [@sterndata](https://wordpress.org/support/users/sterndata/) I mean to say troubleshoot. And i have never ever changed permissions of any file so how could happened. * Moderator [Steven Stern (sterndata)](https://wordpress.org/support/users/sterndata/) * (@sterndata) * Volunteer Forum Moderator * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11347177) * What does the first screen of Health Check say about file permissions? * Thread Starter [jsima](https://wordpress.org/support/users/jsima/) * (@jsima) * [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11360969) * [@sterndata](https://wordpress.org/support/users/sterndata/) I don’t know where/ how to find file permissions using Health Check. So i am going to attach snapshot of site status examined by Health Check. Hope this will help you to find bug. * [https://i.imgur.com/WCaeus3.png](https://i.imgur.com/WCaeus3.png) Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘WordPress Theme Editor Stylesheet File Editor Error’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 9 replies * 3 participants * Last reply from: [jsima](https://wordpress.org/support/users/jsima/) * Last activity: [7 years, 2 months ago](https://wordpress.org/support/topic/wordpress-theme-editor-stylesheet-file-editor-error/#post-11360969) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
