Reported problem in the forum:

I have also problems with archive.php since Piwik 2.1.0.

I am running the process on Synology NAS and thisi is the error message :

============================================================

ps: invalid option -- 'e'
BusyBox v1.16.1 (2014-03-06 14:29:34 CST) multi-call binary.

Usage: ps

Report process status

Options:
w Wide output

The problem seems coming from the fact that the commande "ps -e" is used somewhere but under Synology the "e" option is not valid. Would it be possible to help me to locate where this command is used in the script in order to get rid-off the "e" option ?
