The upload of a zipped file doesn't work in the document tool, why?

From ClarolineDoc

You need to activate Zlib library (http://www.php.net/zlib) in the file php.ini

If Zlib library is activated, verify the limits for the following settings in php.ini :

  • upload_max_filesize
  • post_max_size
  • max_execution_time
  • LimitRequestBody
