Bad URL of an uploaded video in a lesson

[narcisgarcia]

Chamilo LMS 1.11.28

I create a course.
I create a lesson.
There I create a document, because I want to lesson begins with a video.
In the text editor, I embed a simple "Video" -> Server -> There I upload a .webm file, and select it.

After saving this "document", i see it in documents tree. If I click on Preview button, I get the file (browser downloads it). Okay.

If I preview lesson, I see an area to play the video but, when I click it to play, message appears (replaced to example.net):

Media error: Format(s) not supported or source(s) not found
Download File: https://www.example.net/courses/SH1/document/MyVideo.webm

Instead of this URL it should be in my website:
https://www.example.net/lms/chamilo/courses/SH1/document/MyVideo.webm

Then this means Chamilo is not using REQUEST_URI to get real path of contents (lms/chamilo/).
