Please check wp-content/uploads is writable or not.
r u using Windows or Linux?
I am using a mac.
The FTP program i’m using is flow.
just right click on uploads folder then check its properties and see whether it has read write and execute permission.
I had to create the uploads folder myself and the permissions are 755.
And it’s messed up my server, forget it. I’ll stick with HTML & CSS.
If you have tried settings changes as well as CHMOD tricks and nothing works, here is something else to try.
When you upload files from your computer to your online server, this data travels from your computer thru a tmp folder before being saved into wp-content/uploads folder.
Path to this tmp folder is controlled through a line in php.ini file on your server. Depending upon the server setup, you may or may not have access to this file. If this is not setup correctly in your php.ini file, wordpress will try to use a system tmp folder on the server that applications such as wordpress have no access to.
Either update the php.ini file or call your tech support and they can do it for you.
