550 Permission Denied when altering CSS

[ChOpSueY!]

Hello,
I need to custumize the position of #phocagallery-module-ri .phocagallery-box-file. So i placed a margin to this area, saved and tried to overwrite it with the originale css file.

I am getting

Response: 550 phocagallery_module_random_image.css: Permission denied
Error: Upload failed
Status: Retrieving directory listing...

I have set all to 777, nothing takes effect. How can i custumize my css then=?

Best regards

Hi, you should contact your webhosting operator because of setting permissions and ownership of your files and folders. If you cannot overwrite files via e.g. ftp, you need to contact webosting to solve this problem and change ownership of the files and folders.
