Global parameters documents and cron

Hi,

I'm having issues that i think are related to the global parameters or maybe my folder rights.

I installed pojeqtor 6.0.7 on an Asustor NAS.
The structure of folders is :

webfolder |----project 1 Dir
|----projeqtor Dir--|--- view
| |--- tool

....

When i install projeqtor, i have no particular issue or warning.
I can use projeqtor for every purpose (create user, ressources, gantt...)
But when i've tried to upload a profile picture from my computer, i had a warning saying it was not possible.
In global parameters, i managed to fill the values for documents folder and filled the size of doc field. It finaly worked.
I can upload a profile picture but it doesn't show. When i left clic the default picture, it does open my picture.
Also i did not specify any cron info in global settings.

Not having the profile picture showing is no big deal but i'm affraid to have other issues later...
Which values and dir should i use in global parameters ?

Thanks

Thanks, i'll check that..
i'll let you know if i solved the issue as soon as possible.
