Title: Failed to initialize plugin: codesample Last modified: November 20, 2024 --- # Failed to initialize plugin: codesample * Resolved [digitalmaker](https://wordpress.org/support/users/digitalmaker/) * (@digitalmaker) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/) * Hello, * I just installed the latest update of Tutor LMS 3.0. Since then, I’ve been encountering a critical error that makes my modules inaccessible. Additionally, when accessing the course builder, this message appears: **Failed to initialize plugin: codesample**. * I’ve tried clearing the browser cache and the site cache using WP Rocket without success. The problem persists. I’m using WordPress version 6.7, PHP version 8.1.30, and the Flatsome builder 3.18.1. I’m also using Tutor LMS Pro 2.7.6. * I urgently need assistance, please. * Thank you.

How are you? * I am facing the same problem with my website. I have an online course system with Tutor LMS PRO, and after the update, the service stopped. The lessons are not loading, and the layout of the system has changed. As shown in the image in the link: [https://www.canva.com/design/DAGXB1RzIKo/o0tRQoAss-jw6avqbtM10g/view?utm_content=DAGXB1RzIKo&utm_campaign=designshare&utm_medium=link&utm_source=editor](https://www.canva.com/design/DAGXB1RzIKo/o0tRQoAss-jw6avqbtM10g/view?utm_content=DAGXB1RzIKo&utm_campaign=designshare&utm_medium=link&utm_source=editor) There are two images in this link. One shows the Tutor system with how the lessons are appearing, and the second image shows the same error as our friend [@digitalmaker](https://wordpress.org/support/users/digitalmaker/). * I rely heavily on this service, and if you could assist us, it would be fantastic. * Best regards from Brazil. * Lucas Carvalho - This reply was modified 1 year, 6 months ago by [lucasguicar](https://wordpress.org/support/users/lucasguicar/). * [danidile94](https://wordpress.org/support/users/danidile94/) * (@danidile94) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/#post-18149306) * I’m also having the same issue.

I did it immediately as i saw that the 3.0 was not working. Here is a link to a video that shows how to go back to the 2.77 version in case you need it. * [https://www.youtube.com/watch?v=TGyRRw8p90Q&t=45s](https://www.youtube.com/watch?v=TGyRRw8p90Q&t=45s) * [italiantech](https://wordpress.org/support/users/italiantech/) * (@italiantech) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/#post-18150008) * Just like everyone else, I’m having this issue also… [@danidile94](https://wordpress.org/support/users/danidile94/) When you did this, did your course info stay or did it have to be restored? I do not want my course information to go away when downgrading through this method. - This reply was modified 1 year, 6 months ago by [italiantech](https://wordpress.org/support/users/italiantech/). * [lucasguicar](https://wordpress.org/support/users/lucasguicar/) * (@lucasguicar) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/#post-18150142) * Hey everyone!!

To ensure compatibility and proper functionality, both versions of the plugin must be the same. For example, if you’re using Tutor LMS Free 3.0, you’ll need to update your Tutor LMS Pro to the corresponding version. * I hope this resolves the issue for all of you. * [@digitalmaker](https://wordpress.org/support/users/digitalmaker/) [@lucasguicar](https://wordpress.org/support/users/lucasguicar/) [@danidile94](https://wordpress.org/support/users/danidile94/) [@erukoz](https://wordpress.org/support/users/erukoz/) [@abulais](https://wordpress.org/support/users/abulais/) [@hasnainmalik](https://wordpress.org/support/users/hasnainmalik/) [@italiantech](https://wordpress.org/support/users/italiantech/) * [preciousgabraels](https://wordpress.org/support/users/preciousgabraels/) * (@preciousgabraels) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/#post-18157586) * The issue also persists when trying to generate a certificate. I get a nonce error and then the page keeps refreshing. This happens when I set a custom certificate instead of the default ones. I discovered there is an incompatibility issue between the Tutor and Tutor Pro plugins (both are the latest update of 3.0.1) - This reply was modified 1 year, 6 months ago by [preciousgabraels](https://wordpress.org/support/users/preciousgabraels/). * [Nafiz](https://wordpress.org/support/users/urnafiz/) * (@urnafiz) * [1 year, 6 months ago](https://wordpress.org/support/topic/failed-to-initialize-plugin-codesample/#post-18158006) * Hello [@preciousgabraels](https://wordpress.org/support/users/preciousgabraels/), * Thank you for reaching out to us! * Certificate feature is part of the **Tutor LMS Pro** version.
