Hi!

I just installed the plugin, created the store, and wanted to update the store in the WP backend. BUT... :-)... I receive this error on the General page (tools.php?page=datafeedr&mm=general); Temp Directory: Directory not found.

In the directories section, I've tried the set up all directories. Didn't work.
I get this error when doing that:

ERROR:mkdir() [<a href='function.mkdir'>function.mkdir</a>]: SAFE MODE Restriction in effect. The script whose uid is 1086 is not allowed to access /var/www/tmp owned by uid 505() line=537
ERROR:err_dir_cannot_create(/var/www/tmp)
ERROR:err_dir_cannot_create()

cURL is installed btw.

What to do? :-) Thanks :-)
