// PclZip is a PHP library that manage ZIP archives.

// and ‘-‘ for range or ‘,’ to separate ranges. No spaces or ‘;’
// are allowed.
// $p_path : Path where the files and directories are to be extracted
// $p_remove_path : First part (‘root’ part) of the memorized path
// (if any similar) to remove while extracting.
// Options :
// PCLZIP_OPT_PATH :
// PCLZIP_OPT_ADD_PATH :
// PCLZIP_OPT_REMOVE_PATH :
// PCLZIP_OPT_REMOVE_ALL_PATH :
// PCLZIP_OPT_EXTRACT_AS_STRING : The files are extracted as strings and

September 13, 2016 at 2:45 am #967788Hi,
I check JA (JoomlArt) Extensions Manager component at my local and see it needs backup old extensions before upgrading and that why you can see the files setting with permission 0777.
You can create the username manages source code from your hosting with permission full control and you can set the configuration of firewall to accept this username. You will not able to see that bug on your site
Regards
