I just installed User Avatar and it gave me error in activation phase that it is unable to create folder wp-content/uploads/avatar. So I created it manually with 755 rights and next time UA activated correctly. Problem is, that when I try to upload picture, it says that it is unable to move it to folder wp-content/uploads/2011/10 9actual year/month folder. I suppose it is because of access rights there, I have also 755 set on this folder. It is really not recommended to use 777 rights with write permissions, is there any other solution to make UA work?
