Hi all (if anyone is there). I have the same problem. I found great new wordpress themes, tried to upload with Dreamweaver, got the message:
Unable to create remote folder blog/….., Access Denied. The file may not exist, or there could be a permission problem.
I downloaded FileZilla, tried to upload the theme and got the message:
Response: 550 /blog/wp-content/themes/colorful/images/underline.gif: No such file or directory (but it does exist)
Error: Critical error
I then tried to change permission of folders and files with FileZilla and got the response:
550 themes: Operation not permitted.
Although I know very little about all of this, I have created (somehow) a few websites and I urgently need to get my blog going. Is there anyone in the digital universe who can help me, please.
