Resolved Plugin Installation Error – File is writable by others, please fix permissions and try again
It’s the first happen to me. One of WordPress blog gave me this error message when I tried to installed and activated a new plugin: File is writable by others, please fix permissions and try again.
Activation or deactivation of the already installed plugins doesn’t generate this error message. It only happens whenever I tried to install or activate new plugins.
I currently use WordPress 2.7.1 and it was installed using cPanel and automatically upgraded using WordPress Automatic Upgrade like my other WordPress blogs. So there’s nothing different here.
The problem is obviously file permission. But which one?
I changed the permission my wp-content/plugins to 755 and 644 but I still get the same error message.
Finally after testing by changing the file permission one-by-one, I was able to resolve the problem. I’m not sure yet if it’s a permanent solution, but for now I’m able to install and activate new WordPress plugins.
Just in case you happen to experience the same problem, here’s the solution that I use.
Change the permission of these following files to 644:
