I am having the same problem – i’ve looked at the Changing_File_Permissions but still have not gotten any closer to fixing this particular issue
Checking the .htaccess file – what do I need to look for?
I’ve checked the wp-content/uploads file permissions and they are set – I read to deactivate gravity form which did remove the error previously encountered but now even though I can upload it says the following:
Unable to create directory uploads/2015/03. Is its parent directory writable by the server?
