PDF Download

Similar a #3774
download the /vendor folder from the url https://github.com/chamilo/chamilo-lms/releases/download/v1.11.28/chamilo-1.11.28.zip
and replaces the contents of the /vendor folder locally

The error you're seeing indicates that the CssSelector component from Symfony is missing, which is necessary for filtering with a CSS selector. Here's how to fix it:

Install the CssSelector component: Open a terminal in your project directory and run the following command to install the component
rm composer.lock
rm -rf web/ vendor/
composer clear-cache
composer update

Thanks for your answer,

I already got the vendor/ dir when I migrated but the component seems to be missing.

Does that work if I install the component with composer on a QA server and then copy vendor/ dir ? This would generate less downtime

Ok, it worked , thank you.
Maybe it would be great to update the release ?
