Change the permissions on the theme’s files to 766. If you still have problems, try 767 or 777.
how do i do that exactly? in my FTP client? I cannot change the permissions for the footer.php file in my FTP client, I get an error.
When I do it through my FTP client I get: “Make sure that your username and password are entered correctly. If the problem persists, contact your server administrator.”
Contact your hosts. They make have to change the ownership on that theme’s folder. In fact, ask them to change the ownership of wp-content and all of its sub-folders, if possible.
There’s no way for me to change it? How did this happen?
That’s a question you may need to direct to your hosts.
