Im getting this error:
Warning: unlink(e:\hosting\member\sertobon\maite/cache/code_c725750209bacf4971a45bd9c5ca7597.png) [function.unlink]:
Permission denied in e:\hosting\member\sertobon\maite\zp-core\controller.php on line 45

I have set permissions to that particular file but the error is still there.
Does anybody know what could be?

Thanks

What have you set the permissions to? That error means the PHP process does not have permission to delete the file.

Thanks for your reply.
I've set full permissions to the file controller.php but the error is still there.
Im running verion 1.1.4

Thorugh FTP I deleted all the image files in the cache folder and the error message is gone ???

I found the problem. I forgot the add delete permissions to the album and cache folders.
BTW I'm using a Windows 2003 server, just in case if anyone run into the same problem.
Give read, write, execute and delete (RWXD) permissions to the NETWORK user.

Bingo, was about to recommend that. It should be whatever user the web server is running as.
