My images are not showing in my courses

[Suszandara]

Hi,
I am completely new to Chamilo and to LMS in general. But, I do have a lot of experience with other PHP/SQL-based platforms.

Chamilo is installed as a sub-directory of my main website on an Apache server (my web hosting service).

I have a course with 9 learning paths. Each learning path has its own set of images and Appendices that are image- or PDF-based. I have checked my .htaccess file and configuration settings for Chamilo and can find no reason why my images or PDFs would be blocked but none of them are showing in student, teacher or administrator view. I have also read through the Chamilo guide but it is not helpful at all.

The images are jpg format and I uploaded them from my PC to Chamilo > images > gallery. The only image that is showing is my logo, which is PNG format.

The PDF files are linked into the text of the learning path but when I try to save the document I get an error message that reads:

"Not Acceptable
An appropriate representation of the requested resource could not be found on this server.
Additionally, a 406 Not Acceptable error was encountered while trying to use an ErrorDocument to handle the request."

Can anyone help me fix these issues?

Thank you.
