Ok it works. Thanks.

I dont have avatars folder. I'm trying to uploading the avatar from my computer. But I cant.

Which file I have to chmod?

Warning: move_uploaded_file(img/avatars/2.tmp) [function.move-uploaded-file]: failed to open stream: Permission denied in /home/cl2druj4/public_html/profile.php on line 365

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/php5BcuPt' to 'img/avatars/2.tmp' in /home/cl2druj4/public_html/profile.php on line 365

yep

I have a problem with avatars. I cant' upload them. I'm choosing acceptable avatar from my computer, its tiny enough but again I have this error message: The server was unable to save the uploaded file.
What should I do?
