Several authoring issues after a fresh Chamilo 2.0.3 install (learning path editor, quiz editing after Excel import, SCORM, course introduction)

[aubry45230]

Summary

Fresh install of Chamilo 2.0.3 (Docker, PHP 8.3). After installation, several authoring tools misbehave. I'm grouping the issues here for context — happy to split them into separate reports if you prefer.

Environment

• Chamilo: 2.0.3 (installed from chamilo-2.0.3.tar.gz). Note: the chamilo_database_version setting still reports 2.0.0 (see issue 6).
• PHP: 8.3 (official php:8.3-apache image), display_errors at its default (On)
• Database: MariaDB 11
• Web server: Apache 2.4
• Deployment: Docker, behind a Cloudflare Tunnel (HTTPS)
• Host OS: Linux

Issue 1 — Learning path list is not refreshed after creating a learning path

Steps: Course → Learning paths → create a new learning path → go back to the learning path list.
Actual: The new learning path does not appear in the list, so it looks like the creation failed. This leads to creating it again (I ended up with several duplicate rows in c_lp). The learning path is actually created correctly — only the list view is not refreshed. A hard refresh (Ctrl+F5) makes it appear.
Expected: The newly created learning path should appear in the list immediately.

Issue 2 — PHP 8.3 warnings break redirects in the learning path editor

Observed errors:

Warning: Undefined array key "accumulate_scorm_time" in /var/www/chamilo/public/main/lp/lp_add.php on line 239
Warning: Cannot modify header information - headers already sent (output started at .../lp_add.php:239) in .../lp_add.php on line 243

Cause: With display_errors=On, these PHP 8.3 warnings are printed to the page before the header() redirect, which then fails ("headers already sent"), so the action appears to break. Setting display_errors=Off is a workaround, but the underlying undefined-array-key / strict-typing warnings should be fixed (looks related to #8483).
Expected: No PHP warnings; redirects should work regardless of display_errors.

Issue 3 — Quiz questions cannot be viewed/edited after Excel import

Steps: Import a quiz via Excel, then try to view/edit its questions.
Actual: PHP deprecation/warning output breaks the page (same display_errors mechanism as Issue 2), preventing normal viewing/editing of the imported questions.
Expected: Imported questions can be viewed and edited normally.

Issue 4 — SCORM import error + "ghost" learning paths that cannot be deleted from the UI

Steps: Import a SCORM 1.2 package as a learning path.
Actual: Import fails with Undefined constant "SYS_COURSE_PATH". Deleting the resulting (broken) SCORM learning path through the UI does not remove it — it keeps reappearing in the learning path list. The c_lp rows (lp_type=2) and their resource_node entries remain in the database; only a manual SQL cleanup removes them.
Expected: SCORM 1.2 should import without error, and UI deletion should fully remove the learning path (including its resource_node).

Issue 5 — Course "Introduction" cannot be removed from the UI

Steps: On the course homepage, edit the Introduction, clear all its content, and save.
Actual: The Introduction block persists. Clearing + saving does not remove it, and there is no delete control. It could only be removed via the database (c_tool_intro + its resource_node).
Expected: Clearing and saving (or a dedicated delete control) should remove the course introduction.

Issue 6 — Version-check false positive after 2.0.0 → 2.0.3

Actual: After installing 2.0.3, the chamilo_database_version setting still reads 2.0.0. As a result the platform shows a permanent "Chamilo 2.0.3 has been released, please update" security notice, even though 2.0.3 is already installed.
Expected: The database version setting should reflect the installed version so the update notice does not fire incorrectly.

Additional context

Most of these seem tied to PHP 8.3 strict behaviour (warnings/deprecations breaking redirects) and to the resource_node lifecycle not being fully cleaned up on UI deletion. Thanks for your work on 2.x — happy to provide more detail or logs on any of these.

Hi @aubry45230
Sorry to hear that and thank you for reporting.
The version-check issue is fixed in 2.1 (only a few days away).
For the rest, it sounds like maybe cleaning the cache (from the admin interface, system block) might help solve some of these.
Regarding accumulate_scorm_time, could you check in your c_lp table if you have a field called accumulate_scorm_time?
We will review the other ones before the release of 2.1, just to make sure they are fixed.

Hi Yannick, thanks for the quick response.

Cache cleared (both from the admin System block and via
bin/console cache:clear --env=prod) — good news, that did fix a couple of
the smaller glitches.

About accumulate_scorm_time: the field IS present in my c_lp table.

Field Type Null Key Default Extra
accumulate_scorm_time int(11) NO 1
accumulate_work_time int(11) NO 0

So the "Undefined array key accumulate_scorm_time" notice at lp_add.php:239
seems to come from the form POST array rather than from a missing DB column.

One thing that may be worth flagging for 2.1, because I believe it is the
root cause of several of the issues I reported: on PHP 8.3, Chamilo 2.0.3
emits a number of harmless Warning/Deprecated notices. With display_errors=On
they are printed before the header() redirect, which produces
"Cannot modify header information - headers already sent" and silently breaks
the redirect. The underlying action usually succeeded, but the UI reports
failure. Setting display_errors=Off in my PHP config fixed learning path
creation, the Excel quiz import, and saving the course introduction — all in
one go. It might be worth suppressing those notices at the source, since a
default PHP configuration with display_errors=On will hit this.

Two issues that remain after the cache clear:

1. The learning path list does not refresh after creating a new LP. The LP is
   correctly persisted in c_lp, but it does not appear until a hard reload
   (Ctrl+F5). I initially thought creation was failing and ended up with three
   duplicates of the same learning path.

2. Deleted SCORM learning paths (lp_type=2) reappeared in the list after being
   deleted through the UI — leftover rows in c_lp. I had to purge them
   manually through the resource_node cascade. This also triggered an
   "Undefined constant SYS_COURSE_PATH" error.

Environment: Chamilo 2.0.3, PHP 8.3 (apache), MariaDB 11, Docker.

Happy to test a 2.1 release candidate on my instance if that helps.
