Course categories creation breaks

[ywarnier]

Describe
In newly installed 1.11.26 (and possibly 1.11.24) or systems updated where vendor/ and composer.lock was deleted before a composer update, there is an error when creating a new course category.

The error message is:
Fatal error: Uncaught Error: Call to undefined function html_filter() in main/inc/lib/course_category.lib.php:191

The html_filter() function is present in FormValidator.class.php (but not part of the FormValidator class), but apparently it doesn't get picked up.

Apparently, this is not present in systems where vendor/ and composer.json are a bit older, suggesting to me that something might have changed in the composer update process that removed the mapping of the html_filter() function in the autoload files.

To Reproduce
Steps to reproduce the behavior:

1. Install a fresh 1.11.26 or remove composer.lock and vendor/ from an existing system, then "composer update"
2. Go to admin > Courses categories > "Create" icon > Input something > Save.

Hi,
Strange as I made some tests.
2 platforms upgraded under Linux environment ; no problem.
Fresh install under windows : no problem either.

I occured sometimes that you get different behaviour if you use .zip or .tgz version, would this be a clue?

We got the error in 3 fresh installations of Chamilo 1.11.26 under Linux Debian, using Git (not using .zip or .tgz) and doing composer update.
Also we tried:
`rm composer.lock

rm -rf web/ vendor/

composer clear-cache

composer update`
After installation, but it doesn't fix the problem

Just removed and reinstalled chamilo1.11.26 and I also get an error.
I suspect a cache that wasn't empty.
The error I get is 500 => Page not available

I confirm that the creation of course categories does not work, and the editing of sublanguages works but problematically, for example, you can not edit the created sublanguage name.
@Coursenligne What cache ?

[Coursenligne]

I'm not sure, but there must be somwhere a cache that was persistant as after removing and reinstalling the issue arises.
The strange thing is I made an upgrade on a production server and I don't get it (obiously I don't want to generate it.
I just have on all platforms the issue of LP exports that becomes impossible to modify as seen (when re-imported) as an external SCORM packet.
This is for the moment the biggest issue....

IF when copying your courses or importing/exporting the SCORMs/Studio Editor are empty:
Simply set allow_import_scorm_package_in_course_builder in app/config/configuration.php to true.

Hello Damien,
I'm the same Coursenligne that on the forum :)
I already activated this option, but here, the story is different.
I had te categories working on one of the platforms after upgrade (and it still seems to work) and I suspect something that was in cache and therefore persistent.
I did a fresh install on my own PC yesterday and can confirm the bug.
