Hello

 

I really need help for this, everytime i try to upload a big file on the file picker (about 49meg), i have this error message:

ERROR: Chaîne JSON non valide

Internal Server Error
The server encountered an internal error or
misconfiguration and was unable to complete
your request.
Please contact the server administrator,
 [no address given] and inform them of the time the error occurred,
and anything you might have done that may have
caused the error.
More information about this error may be available
in the server error log.

It doen't give me any clue and nothing on php log either...

 

I have looked on the forum and looks like i m not the only one, so i opened a Moodle Tracker but it has been immediately closed.

Here another exemple:http://moodle.org/mod/forum/discuss.php?d=153322#p796850

I need advise now on how to deal with that....

I enclosed my php info
